storm pasture Hi guys im trying to change my windows drive from MBR to GPT without loosing win...

you can change it in disk manager

#

right click on the drive you want to do it and select convert to gpt

#

If you are still having issues I litterally did this yesterday

#

https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10#:~:text=Convert MBR to GPT partition style (online)&text=system is operational.-,To convert a drive from MBR to GPT on Windows,Enter%3A mbr2g

Doing the offline option worked perfectly.

#

hey could someone help

#

i am trying to convert my ssd from mbr to gpt but it always say cannot find OS partition

#

also i don't care if i need to reset my pc

#

my problem is that i am trying to convert from legacy to uefi and i can't do that just from simply changing it from bios because it won't boot

#

and if reinstall windows i think it will automatically be place on legacy mode

#

so what can i do

#

#

?

#

so?

storm pasture Apr 22, 2023, 2:42 PM

#

#

in size to shrink

#

@hexed oracle

hexed oracle Apr 22, 2023, 2:47 PM

#

i can't

#

look at the screenshot

#

@storm pasture

storm pasture Apr 22, 2023, 2:49 PM

#

idk then u have some dodgy hard drive

hexed oracle Apr 22, 2023, 2:50 PM

#

how can i reinstall windows but with uefi mode not legacy?

storm pasture Apr 22, 2023, 2:50 PM

#

you cant unless you have a GPT

#

your prob gonna need a new hard drive

hexed oracle Apr 22, 2023, 2:52 PM

#

bruh ain't no way

storm pasture Apr 22, 2023, 3:07 PM

#

you need GPT for win 11

#

what are your system specs

mortal junco Apr 22, 2023, 3:11 PM

#

hexed oracle

is that harddrive?

storm pasture Apr 22, 2023, 3:12 PM

#

mortal junco is that harddrive?

wouldnt matter you can GPT hard drives

mortal junco Apr 22, 2023, 3:12 PM

#

ok but the screenshot is trying to shrink the partition?

storm pasture Apr 22, 2023, 3:13 PM

#

yeah to have a OS partition

mortal junco Apr 22, 2023, 3:13 PM

#

looking at his disk management screenshot

#

its super weird layout

#

why the "system reserved" on a different drive

#

lmao

#

that what might trigger the "cant find os"

#

also please make a new thread, people wont click on resolved thread

hexed oracle Apr 22, 2023, 3:31 PM

#

mortal junco why the "system reserved" on a different drive

ik i am super confused as well idk at this point

#

what is happening

mortal junco Apr 22, 2023, 3:32 PM

#

Yeah that might be the issue

#

Really the simplest way is just to reinstall KEKW

#

make sure to unplug or disable thru bios for other drives

hexed oracle Apr 22, 2023, 3:36 PM

#

wait

#

it worked i can do it now

#

@storm pasture

storm pasture Apr 22, 2023, 3:37 PM

#

ok

#

run the mbr2gpt command

hexed oracle Apr 22, 2023, 3:39 PM

#

same error happened

#

but what is weird is that my os is in disk 1

#

not 0

storm pasture Apr 22, 2023, 3:40 PM

#

right what drive is your windows on

hexed oracle Apr 22, 2023, 3:40 PM

#

disk 1 and the error is saying that couldn't find os partition on disk 0

storm pasture Apr 22, 2023, 3:40 PM

#

right

#

unplug whatever drive doesnt have windows on

#

obv turn ur pc off first

hexed oracle Apr 22, 2023, 3:41 PM

#

well my laptop needs to be cleaned anyway so ok

mortal junco Apr 22, 2023, 3:42 PM

#

my bet that he wont boot

storm pasture Apr 22, 2023, 3:42 PM

#

mortal junco my bet that he wont boot

thats the plan

#

if it doesnt boot, you have some dodgy ass windows install

mortal junco Apr 22, 2023, 3:42 PM

#

how do you gonna access the windows without booting

#

thats what i said earlier...

#

he has janky ass setup partition

storm pasture Apr 22, 2023, 3:42 PM

#

yeah but you can still get into windows

#

thru recovery

#

if the drive with windows is still plugged in

hexed oracle Apr 22, 2023, 3:43 PM

#

i am gonna try and see what happens

mortal junco Apr 22, 2023, 3:43 PM

#

but there wont be boot entry to anywhere

#

since it lived in the hdd

#

according to the screenshot anyway

storm pasture Apr 22, 2023, 3:44 PM

#

mortal junco but there wont be boot entry to anywhere

as long as there is A drive with windows, it will boot to windows

mortal junco Apr 22, 2023, 3:44 PM

#

aight we'll see

storm pasture Apr 22, 2023, 3:44 PM

#

unless the windows install itself is fucked

#

in which case its a matter of just wiping all drives

hexed oracle Apr 22, 2023, 3:45 PM

#

storm pasture unless the windows install itself is fucked

i have a feeling that it is

storm pasture Apr 22, 2023, 3:45 PM

#

hexed oracle i have a feeling that it is

do you know how to install windows thru USB?

hexed oracle Apr 22, 2023, 3:45 PM

#

yeah

storm pasture Apr 22, 2023, 3:45 PM

#

wipe ALL of your drives completely

#

reinstall windows

#

make sure to write down ur windows key somewhere as it might still ask

#

the drive might still be in MBR afterwards in which case its just run the command

hexed oracle Apr 22, 2023, 3:47 PM

#

storm pasture make sure to write down ur windows key somewhere as it might still ask

😶

storm pasture Apr 22, 2023, 3:48 PM

#

hexed oracle 😶

run cmd in admin

#

wmic path softwarelicensingservice get OA3xOriginalProductKey

#

ur windows key will appear

#

if you have one

hexed oracle Apr 22, 2023, 3:49 PM

#

ik i am just saying that i don't have one🙂

storm pasture Apr 22, 2023, 3:49 PM

#

welp that might be half the damn reason ur having the problems your currently having

#

wish you said this earlier

mortal junco Apr 22, 2023, 3:49 PM

#

hexed oracle ik i am just saying that i don't have one🙂

LUL

#

no one does, dont worry

storm pasture Apr 22, 2023, 3:50 PM

#

mortal junco no one does, dont worry

well yeah ik but it does cause problems with this sorta stuff

mortal junco Apr 22, 2023, 3:50 PM

#

first of all

#

no it doesnt

hexed oracle Apr 22, 2023, 3:50 PM

#

linus himself doesn't have one

mortal junco Apr 22, 2023, 3:50 PM

#

second of all, if it does, how the installer know if they have a key or not?

#

the partitioning happens before install

storm pasture Apr 22, 2023, 3:50 PM

#

reg editpr

#

XD

mortal junco Apr 22, 2023, 3:51 PM

#

third of all, asking for license is after youre finish installing

storm pasture Apr 22, 2023, 3:51 PM

#

4th of all, the mbr2gpt command only works on certain versions of windows from what ive read

#

which would explain why its not converting

mortal junco Apr 22, 2023, 3:52 PM

#

no

#

it doesnt work because the janky partition

#

the boot partition on disk 0

#

meanwhile the windows itself on disk 1

#

your only solution here just to reinstall the windows

#

unplug the non-windows drive beforehand if possible

#

make sure youre on uefi with csm disabled

#

then reinstall windows

#

if all gucci, replug the hdd

#

remove the extra partition from old windows

#

and youre set

hexed oracle Apr 22, 2023, 4:38 PM

#

yeah my windows installation is fucked it didn't boot

#

i knew i shouldn't have relied on that store to install windows for me

#

i bought it from them and said its ok let them install windows for me so i can save time

#

isn't there a software i think called rufus which i can install windows with uefi mode through usb?

mortal junco Apr 22, 2023, 4:43 PM

#

told ya it wont boot

#

yes

hexed oracle Apr 22, 2023, 4:44 PM

#

i guess i am gonna do that

#

is there a tutorial for it so i don't mess it up?

mortal junco Apr 22, 2023, 4:44 PM

#

mortal junco make sure youre on uefi with csm disabled

doublecheck this too on your laptop

#

just screenshot the rufus setting later

hexed oracle Apr 22, 2023, 4:44 PM

#

ok

#

oh btw i am not on uefi i am on legacy

#

that's why i am doing this whole thing to enable uefi mode

mortal junco Apr 22, 2023, 5:00 PM

#

yes, we basically just doing it from scratch

#

uefi mode with csm disabled

#

and rufus on gpt + uefi(noncsm)

hexed oracle Apr 22, 2023, 5:04 PM

#

how do i check that csm in disabled?

#

and also there are different versions of rufus which one?

broken fern Apr 22, 2023, 5:05 PM

#

Go into your BIOS. It's usually within a BOOT menu... varies from board to board

hexed oracle Apr 22, 2023, 5:14 PM

#

i don't even have csm

broken fern Apr 22, 2023, 5:20 PM

#

If it doesn't say CSM, I know MSI boards don't specifically state that, but they have a "UEFI only" which is the same thing.

hexed oracle Apr 22, 2023, 5:21 PM

#

where is it located at?

broken fern Apr 22, 2023, 5:22 PM

#

Would normally be under your Boot menu in BIOS.

hexed oracle Apr 22, 2023, 5:23 PM

#

you mean in boot priority?

broken fern Apr 22, 2023, 5:24 PM

#

Possibly somewhere in that same vicinity, but it varies from board to board. Make / model?

hexed oracle Apr 22, 2023, 5:25 PM

#

i have laptop lenovo legion 5 so idk

#

rn_image_picker_lib_temp_49a404ff-df02-4ede-959d-f11964a5ad1f.jpg

#

is it in this section?

#

@broken fern @mortal junco

mortal junco Apr 22, 2023, 5:35 PM

#

so boot mode set to uefi

#

and maybe after setting it to uefi

#

the "csm" option might show up

#

or it says "pure uefi" that might suffice

hexed oracle Apr 22, 2023, 5:39 PM

#

nah still not there

#

@mortal junco is it in the boot section?

mortal junco Apr 22, 2023, 5:40 PM

#

no, but that might not be necessary

#

as it says "pure uefi"

hexed oracle Apr 22, 2023, 5:40 PM

#

yeah i can't find that either

mortal junco Apr 22, 2023, 5:41 PM

#

well ure good to go

#

just need rufus, usb drive and iso

hexed oracle Apr 22, 2023, 5:42 PM

#

ok but what is usb legacy?

#

i have that as an option

#

should i disable it?

mortal junco Apr 22, 2023, 5:42 PM

#

post another pict

hexed oracle Apr 22, 2023, 5:43 PM

mortal junco Apr 22, 2023, 5:43 PM

#

no idea what that is

#

just disable it LUL

hexed oracle Apr 22, 2023, 5:44 PM

#

nvm figured out what it is for

#

it won't interfere with anything

#

@mortal junco which version of rufus should i download?

#

there is protable version, arm64 ver,arm ver and normal version

mortal junco Apr 22, 2023, 5:49 PM

#

normal should be fine

hexed oracle Apr 22, 2023, 5:49 PM

#

ok

#

@mortal junco where can i find a windows iso file?

mortal junco Apr 22, 2023, 5:57 PM

#

hexed oracle Apr 23, 2023, 8:36 AM

#

@mortal junco do you any other source where i can download the iso file

#

mortal junco Apr 23, 2023, 8:42 AM

hexed oracle Apr 23, 2023, 5:50 PM

#

@mortal junco should i delete the system reserved partition on the second hard drive?

mortal junco Apr 23, 2023, 5:53 PM

#

hexed oracle Apr 23, 2023, 5:56 PM

#

#

hey so

#

rn_image_picker_lib_temp_a4e2774d-04c5-4bd0-8d06-3275a0f6be07.jpg

#

i removed it from the file explorer but it is still on disk management should i also delete it from there?

#

@mortal junco

mortal junco Apr 23, 2023, 6:05 PM

#

cant right click to delete?

hexed oracle Apr 23, 2023, 6:07 PM

#

i think i could but i just wanna make sure first

mortal junco Apr 23, 2023, 6:07 PM

#

well deleting from file explore wont do jackshit

#

so you gotta delete from disk management

#

so it only has 1 partition for the entire disk

hexed oracle Apr 23, 2023, 6:08 PM

#

i deleted it

mortal junco Apr 23, 2023, 6:08 PM

#

so it has 1 partition now?

hexed oracle Apr 23, 2023, 6:09 PM

#

yeah not exactly the partition got deleted but it is unallocated now

mortal junco Apr 23, 2023, 6:09 PM

#

well merge it to the rest

hexed oracle Apr 23, 2023, 6:09 PM

#

do you know i can merge it with the other partition

#MBR to GPT
