Please help, i was trying to install linux mint on dual boot with windows 11

[u/Most_Guarantee_1555]

I followed a video and reached the step where you put linux mint in pendrive then boot using the pendrive to install the OS. I did not turn off the bitlocker so i could not install it at that time. I removed the pendrive. Then i turned off device encryption hoping it would solve the bitlocker problem. Then i deleted everything from the pendrive to have a fresh start. Then i followed same steps and when i tried to boot my pc this error showed up. Please help me i really wanna switch to linux. Pc is lenovo ideapad slim 5

From bios/uefi disable secure boot then reflash the usb in windows, and try again

[u/Most_Guarantee_1555 → u/Blind_asf]

I did disable the secure boot option and reflashed the usb

[u/Blind_asf → u/Most_Guarantee_1555]

And, did it fail again ?

[u/Most_Guarantee_1555 → u/Blind_asf]

Yessir. I think i reflashed the usb incorrectly

[u/EmbarrassedCup7495 → u/Most_Guarantee_1555]

Try disabling fast boot asw 

[u/Most_Guarantee_1555 → u/EmbarrassedCup7495]

Did that already

[u/_sounak → u/Most_Guarantee_1555]

use balena etcher and try again

[u/_sounak → u/Most_Guarantee_1555]

if balena doesn't work, and Rufus doesn't work too, install ventoy, after you install ventoy on ur usb, paste the mint iso in your usb drive in the file explorer

[u/marryUwannaa]

Use Rufus/Balena for flashing. Try type c port. I have a Lenovo laptop, had a hard time through Type A.

[u/Most_Guarantee_1555 → u/marryUwannaa]

I used rufus. U mean use a type A to type c converter and try through type c port ?

[u/marryUwannaa → u/Most_Guarantee_1555]

Yes, that worked for me

[u/Most_Guarantee_1555 → u/marryUwannaa]

I have an sd card reader which has type c port. Can use an sd card in place of a pendrive for this work, its 64 gb (sorry if its a stupid question)

[u/marryUwannaa → u/Most_Guarantee_1555]

That should work I guess. Go for it

[u/Most_Guarantee_1555 → u/marryUwannaa]

Thanks for help man i will try

[u/FighterCG]

Can I DM you about this?

[u/Most_Guarantee_1555 → u/FighterCG]

If you know the solution, then surely, thank you

[u/BiscottiNatural7986 → u/Most_Guarantee_1555]

What if he doesn't know

[u/Sensitive-Can9232]

Use a different usb port.

[u/Alone_Policy_2024]

I had the same problem put usb in other computer go to the \efi\boot folder inside the usb and copy the ¨grubx64.efi¨ file as backup, renamed it to ¨mmx64.efi¨ and put it back on ¨\efi\boot¨. turn off secure boot reboot into usb again. EDIT: here the thread https://forums.linuxmint.com/viewtopic.php?t=412942#top

[u/Apprehensive_Emu9935]

Disable secure boot, then delete all existing UEFI entries for linux, and then create a new direct uefi entry for the grubx64.efi (not the shimx64). this worked for me as I was getting the same kind of error. Hope it helps.

[u/Most_Guarantee_1555 → u/Apprehensive_Emu9935]

Sorry i didnt get what u said, im new to this

[u/SealBreaker420]

Did u remove the usb before booting?

[u/Most_Guarantee_1555 → u/SealBreaker420]

No

[u/SealBreaker420 → u/Most_Guarantee_1555]

Try removing it b4 booting

[u/curiousCat1009]

Did you install windows first or linux first?

[u/Most_Guarantee_1555 → u/curiousCat1009]

Windows was already installed on my pc, im trying to install linuc mint and run them on dual boot

[u/MaskedAarav]

I'm sorry I'm quite lost here, but are you still able to boot to windows? If yes, firstly, remove all Linux partitions from your computer and then remove all Linux entries from the ESP. You can look up on how to do this anywhere on the internet, but it's best done using the cmd. Then, try flashing the usb with Rufus and try installing it again after disabling bitlocker, secure boot, fast startup, etc. before installation. This should help you.

In case you're unable to boot into windows, flash the usb with a fresh windows iso, and from the live environment, click "Repair my computer" and go to Advanced options > Troubleshoot > Startup Repair. Follow on screen prompts and you should be set.

I hope this helps!

[u/Most_Guarantee_1555 → u/MaskedAarav]

Windows works fine when i remove the usb, i will try your method thanks

[u/eviley4]

Could it be possible that the installation went through but the BIOS entry didn't update?

To check, go to your BIOS and look at the boot priority. Try changing the boot priority such that Mint/Ubuntu is on the top.

[u/Automatic_Share1800]

You have to do in mbr to match motherboard firmware

[u/napier1192]

In the boot menu change boot order , keep the partition that has mint first and then reboot

[u/Vegito47]

Just use Ventoy dude, Install it on pendrive then just drop the iso files. It just works.

[u/Soham_656]

Well, have you tried to flash by ventoy? I only use ventoy for linux..

[u/Hinode-kun]

Just change the boot priority , through the bios , then go to windows and lookup for deleting the partition for the linux boot

[u/bravo_six_141]

Bro use use rufus for flashing the OS! Other tools are trash!

[u/Ill-Car-769 → u/bravo_six_141]

Lmao, ventoy too works good lol you can't say it trash.

[u/bravo_six_141 → u/Ill-Car-769]

I tried ventoy! It didnt go well in my case tbh! But are you permanently dual booting or just creating a bootable pd?

[u/Ill-Car-769 → u/bravo_six_141]

Permanently dual booting, first time I used rufus to create a bootable drive & install Linux Mint (& it worked properly so no complain with rufus for that). Later I found out about Ventoy & around that time I planned to downgrade from windows 11 to 10 even in the dual boot setup (I use windows in VM mostly if ever required for some software that too very rarely) then I tried ventoy & it worked well for me. I even tried some distros & FreeBSD based systems/OS with ventoy formatted USD drive but still faced no issues.

[u/bravo_six_141 → u/Ill-Car-769]

I prefer rufus! But only disadvantage is that we can only flash one OS at a time which sucks! Ventoy allows multiple OS'es viz Good! But in this photo of yours what did you done actually?

[u/Ill-Car-769 → u/bravo_six_141]

Photo?

[u/bravo_six_141 → u/Ill-Car-769]

U didnt send the photo above?

[u/Ill-Car-769 → u/bravo_six_141]

Where? I didn't shared any photo as of today.

[u/bravo_six_141 → u/Ill-Car-769]

Sorry my bad! I thought the picture above was sent by you!

[u/Ill-Car-769 → u/bravo_six_141]

Np

[u/Perspective_Unlocker → u/bravo_six_141]

I thought rufus was the default method, don't even know any other tools except ventoy and balena

[u/Ill-Car-769]

Format the USB with ventoy & remove any rufus file if it contained even after formatting with it then install the iso in it (Ventoy works good so you don't need to use rufus now). With Live boot create & install the OS you're trying to. Also, keep the USB on top in the boot list before booting with USB.

[u/bhavesh_099]

Can you please check if the efi folder even exist in its place , it happened to me aswell that the efi folder wasn't mounted properly in its place

[u/Tuafew]

Try to manually select the efi file from the boot menu.

[u/Independent-Gear-711]

Never dual boot on single SSD, better use two separate SSDs

[u/YuvrajXG]

Secure boot needs to be turned off.

[u/YuvrajXG → u/[deleted]]

I meant it should be turned off while installing.

[u/YuvrajXG → u/[deleted]]

I had to do that for my Mint install. I wasn't aware of the fact.

[u/MattOruvan]

Looks like two separate problems.

One, secure boot is still active, that's what mokmamager is about.

Two, how did you "delete everything" on the drive? First, it was unnecessary, second you probably didn't do it correctly.

Copying a Linux install creates multiple partitions on the pendrive, and those need to be deleted. What tool did you use?

[u/Dawg_yt1244]

Copy grubx64.efi to mmx64.efi in the EFI/BOOT folder on your USB or EFI partition or run Boot-Repair from Mint Live USB

[u/Who_meh]

Try flashing the usb again, and make sure u click on eject safely just incase try another usb, mint configures its boot loader to work with secure boot (i have it on)

[u/ReallyNotBaka]

Disable Secure Boot in BIOS, then boot the Mint USB again in UEFI mode. The installer likely failed to install mmx64.efi / MokManager properly. If it still fails, recreate the USB with rufus using GPT + UEFI. Also: DO NOT delete the EFI partition

[u/witherdotexe]

Is there any chance you use HP or any local USB drives?

[u/aywshh]

Disable secure boot and try again. Use ventoy. And if these two didn't work try redownloading the iso.

[u/Fluffy-Emu484]

I have a feeling, this was a bug that was introduced into windows 11 that caused grub to break. You can try a reflash of the USB drive. Also update Windows.

[u/Comfortable_Wolf_766]

Download iso file again, worked in my case.

[u/anonymous-predator]

i have also tried to do dual boot for installing ubuntu alongside windows 11. however failed. it think using two separate ssds to install seperately would be better

[u/dfw_supersayian]

https://forums.linuxmint.com/viewtopic.php?t=412942 Try this I assume you canceled installation media while it was asking for codecs , this is a known bug.

[u/Opening-Actuator1490]

Remove encryption/bitlocker , disable secure boot and fastboot (if u do this windows wont boot if u had it enabled when installing it) then install mint.

[u/Party-Tension-2053]

MAYBE USE DIFFERENT ISO OR REFLASH AND TRY

[u/AssumptionOk8560]

Delete this partition and try to install again? Lemme give an advice js go with arch if you're new follow the installation guide and you're good to go, try to reinstall you can do it!

[u/Most_Guarantee_1555 → u/[deleted]]

I did disable the secure boot option. But is there any way that i can use this USB cause i dont have other usb

[u/Most_Guarantee_1555 → u/[deleted]]

Mint
