Dualbooting Windows - Linux Error | Linux Mint Community🍵 | Page 1

#

run up Windows, use run box to launch msinfo32 and check BIOS BOOT MODE: type and confirm that here.

#

If you want to redo the Windows to UEFI boot mode, the SSD must be in GPT partition layout style. you can check that in Disk Management. hover over the words "disk 0" (whatever the SSD is), right-click> Properties> Volume tab

#

then u need a 16 GB thumb drive prepared with Ventoy (GPT option from its menu) then put fresh Windows installer ISO on it, plus Linux Mint.

#

You'll need the Mint iso for cleaning or Boot Repair tool possibly

stoic peak Jul 16, 2024, 12:35 AM

#

You can't have a legacy and UEFI boot at same time. Both systems must use same boot mode. Reinstall windowz clean in UEFI mode then same with mint.

potent ice Jul 16, 2024, 2:29 PM

#

its multiboot flasher utility. However, if you've made the usb with media creation tool, just use that.

#

as long as u boot it as a uefi usb device

This btw @olive walrus

#

Bios mode should be UEFI only

#

Then reinstall your systems so they boot in pure UEFI

potent ice Jul 16, 2024, 2:33 PM

#

ya if the OEM did that, you'll have to reinstall

#

olive walrus Jul 16, 2024, 2:34 PM

#

Also I got 2 hdds and 1 sdd

stoic peak Jul 16, 2024, 2:34 PM

#

You could convert windowz to GPT but it may not be a clean conversion

#

So better backup and reinstall

potent ice Jul 16, 2024, 2:35 PM

#

that's the SSD?

olive walrus Jul 16, 2024, 2:35 PM

#

Yup the sdd where Windows is installed

potent ice Jul 16, 2024, 2:36 PM

#

So u either redo the whole thing, OR just reinstall Mint as legacy

olive walrus Jul 16, 2024, 2:36 PM

#

I don't care whatever you guys think is the best

#

But why is the B: drive also MBR?

#

The drive where linux is installed?

potent ice Jul 16, 2024, 2:37 PM

#

olive walrus But why is the B: drive also MBR?

what's on it?

olive walrus Jul 16, 2024, 2:38 PM

#

I put all my personal files on that drive because its 2tb

stoic peak Jul 16, 2024, 2:38 PM

#

olive walrus I don't care whatever you guys think is the best

You should use pure UEFI + GPT

olive walrus Jul 16, 2024, 2:38 PM

#

and linux mint made a partion on that b: drive of 400gb

potent ice Jul 16, 2024, 2:38 PM

#

it can still have that partition scheme, but Mint happened to install via uefi cuz of the way u booted the usb installer media

stoic peak Jul 16, 2024, 2:38 PM

#

Use legacy MBR only when you can't use UEFI/lack it

potent ice Jul 16, 2024, 2:39 PM

#

up to u how much time u want to spend. I would just reinstall Mint as legacy

stoic peak Jul 16, 2024, 2:40 PM

#

Legacy won't do as it will limit the partitions to 4 max

potent ice Jul 16, 2024, 2:40 PM

#

then its grub will happily boot windows

olive walrus Jul 16, 2024, 2:40 PM

#

Okay

#

Tell me how to do that please

#

How to reset mint to legacy

potent ice Jul 16, 2024, 2:41 PM

#

turn on csm/legacy, and boot mint live usb as a plain usb device

stoic peak Jul 16, 2024, 2:41 PM

#

You should use UEFI when available

olive walrus Jul 16, 2024, 2:41 PM

#

Uhh

#

It doesnt matter, I have plenty of time

#

to reset windows

potent ice Jul 16, 2024, 2:43 PM

#

then redo that

stoic peak Jul 16, 2024, 2:43 PM

You can do that or clean install windowz

#

Then you install mint on UEFI mode

potent ice Jul 16, 2024, 2:44 PM

#

stoic peak Then you install mint on UEFI mode

already is

olive walrus Jul 16, 2024, 2:44 PM

Anyways try that

potent ice Jul 16, 2024, 2:45 PM

Done

stoic peak Jul 16, 2024, 3:12 PM

#

Boot to your windowz ISO

#

Then do the video

#

I even linked official MS docs

olive walrus Jul 16, 2024, 3:13 PM

#

I have selected the usb from UEFI boot sources

potent ice Jul 16, 2024, 3:13 PM

#

olive walrus I have selected the usb from UEFI boot sources

good

olive walrus Jul 16, 2024, 3:13 PM

#

Okay!

#

Its installing!

olive walrus Jul 16, 2024, 3:37 PM

#

Uhh

olive walrus Jul 16, 2024, 3:38 PM

#

stoic peak Boot to your windowz ISO

Grub doesnt appear?

#

It just boots directly into windows now?

olive walrus Jul 16, 2024, 3:38 PM

#

potent ice good

.

olive walrus Jul 16, 2024, 3:41 PM

#

stoic peak I even linked official MS docs

My disk is now GPT

#

But when I boot my PC

#

It opens into WIndows

#

No grub menu

#

Linux just boots normally

#

Is it something with the boot priority?

#

I disabled fast startup...

#

could the boot order be the problem?

#

I can boot linux from going into the bios and selecting 'Ubuntu"

potent ice Jul 16, 2024, 4:49 PM

#

so probably what happened is the bootloader for Mint was put on the SSD. that got redone when Windows reinstalled

#

basically, all u really need to do is set the operating system you most usually use to the top of the UEFI boot priorities in the BIOS

#

When you want to switch to the other one, you simply press the BIOS Boot menu key at startup, and it will show a small blue screen of other bootable things, and u pick the other OS.

#

I could be wrong on the presumption of Grub having been on the SSD. It may have been on the hard drive, in which case grub's still there, it just may need an update or boot repair .

olive walrus Jul 17, 2024, 10:42 AM

#

Okay!

#

Tbh I like this more instead of selecting a OS in grub
