when booting from supergrub and then picking, "test for os", i just get a bunch of terminal messages which do absolutely nothing. pressing esc aborts this and brings me to the cmd line where i can exit. Im dual booting windows and linux on two different discs. How do i fix this?

copper mortar

#

because my bios doesnt support booting from another disk

copper mortar
west gull
#

i have mint on one hdd and windows on one ssd

#

my bios doesnt allow me to boot between the two

#

only the ssd

copper mortar
west gull
#

uefi

copper mortar
west gull
#

no

#

it doesnt show up

#

its impossible for me unless i flash my bios to a newer version

#

i made a post about this a few months ago, i got mint working with supergrub but i havent touched it since

#

for some reason i cant get it to work anymore

#

if ur able to boot to usb stick u are able to boot another drive

west gull
#

it doesnt recognise the hdd

#

its an internal hdd, comes with the desktop

torn holly
#

show the bios screens

west gull
#

i cant right now, im away from my desktop but i can show you my last post

copper mortar

#

it's probably some "ADD device" setting to do in the BIOS

west gull
#

ill see when i get back home

torn holly
#

just gotta find it, and add the other drive, or the "ubuntu" loader of the other drive

#

also possible that Windows somehow turned Secure Boot back on, and that's why supergrub is now failing

west gull
#

i turned secure boot off

#

before i booted into supergrub

#

i double checked to see if my bios was correct when i booted supergrub

#

im pretty sure everything is fine

torn holly
#

dont do test for OS then. just pick manual boot. choose 'Linux" in the orange list.

west gull
#

i tried that

torn holly
#

and hit enter on vmlinuz (the kernel)

copper mortar
# west gull i tried that

perchance try to use boot repair because your bootloader got broken with windows updates as you didn't touch Linux for a few months and now supergrub can't find it?

west gull
#

ok

#

im back

#

ill take a pic of my bios

torn holly
#

also check in Hard Disk drive priority

west gull
#

boot filter can only show 1 mode

torn holly
#

which is?

west gull
#

uefi

torn holly
#

enable CSM, maybe mint got installed as legacy

#

after enable csm, recheck the boot filter

copper mortar
torn holly
#

and recheck available hard disk priorities

west gull
#

ok

#

it’s on legacy now, the hard disk priority shows nothing now

torn holly
torn holly
west gull
#

it’s on legacy

torn holly
#

it ought to show at least another hard drive somewhere in there.

west gull
#

my bios is just old ngl

torn holly
#

worse comes to worse, u can do a boot repair with manual options, and tell it to reinstall grub to the win-boot-manager partition (probably nvme0n1p1)

west gull
#

idk this seems unnecessary, I rather just use super grub as a temporary solution

torn holly
#

u wouldnt have to use an additional usb to start linux if what I just said works.

#

u just need the mint live usb, and its boot repair tool

#

anyway, if u made change in BIOS now, exit without saving them

copper mortar
torn holly
#

or change them back

torn holly
#

it just fires up the linux kernel on a disk

copper mortar
torn holly
#

eh it can if u direct it to, but I've seen it show a list of bootable linux kernels too

west gull
#

the bootloader is fine

copper mortar
west gull
#

i rather keep the two systems on individual disks

torn holly
#

ok so boot the supergrub thing

west gull
#

im pretty sure the only reason i wasnt able to boot was because i flashed supergrub wrong

copper mortar
west gull
#

the mint bootloader is fine

torn holly
#

it was working before though, the supergrub way

west gull
#

yeah but i had to reflash the usb for something else

torn holly
#

ohh

#

should just use Ventoy

west gull
#

ye

torn holly
#

then u dont have to unflash/reflash

west gull
#

good idea actually

#

its a pretty big usb

torn holly
#

and use gpt in the setup options in ventoy, for guaranteed best performance on the most picky of modern BIOS's

west gull
#

still doesnt fix my supergrub problem though

copper mortar
west gull
#

what version do i pick

torn holly
#

windows

#

or whatever thing ur setting up on

#

ventoy it once, (properly) and u can use it for life in a multitude of purposes

#

then once ventoy is installed, slap the supergrub img onto it

#

and boot it up and it should work when u choose manually boot an OS, and scroll the list for Linux.

west gull
#

uhhhhhh

torn holly
#

why's it showing two drive letters?

#

kek

west gull
#

no clue

torn holly
#

better be careful

#

check in file explorer. u only want ONE usb thing plugged in during this operation

west gull
#

yes its just

torn holly
#

no phones, no nothing, just mouse and one flash drive.

west gull
#

ahhh

torn holly
#

then confirm the drive letter of the flash drive in Explorer,

#

and confirm upon re-running Ventoy2disk

west gull
#

still doesnt work

torn holly
#

what is that from?

west gull
#

ventoy log.txt

torn holly
#

replug the flash drive

#

close ventoy

#

reinsert drive. confirm drive letter in explorer.

#

re-run ventoy.

#

and make sure the options match the picture I sent precisely.

west gull
#

i cant find the drive in the explorer

torn holly
#

open Windows Disk Management and show

west gull
torn holly
#

what size is the USB stick supposed to be (advertised size)

west gull
#

250gb

torn holly
#

is it Acer (C:) ?

west gull
#

no

torn holly
#

reboot the machine, take the usb out first

#

should have stopped before hitting "Install" when u saw TWO drive letters showing up in Ventoy.

#

can also use that one.

#

as long as ur thumbdrive shows up again.
