Linux Dual-Boot Fixing the EFI FAT32 UUID

[digital spade]

The best thing you can do right now is state the problem so we understand it. Which means a screenshot of your partition layout from a GUI tool.

[obtuse glen]

Sda1 only or all of them?

[digital spade]

The drive that gives you trouble, and only that drive.

[obtuse glen]

Is this enough? @digital spade

[digital spade]

I am beginning to understand your trouble. You have a partition with a partial file system. How did you manage that?

[obtuse glen]

I was resizing it and removed the usb by error ( the usb i use to run linux mint to resize partitions)

[digital spade]

I am not sure if that is recoverable without a full reinstall.

[obtuse glen]

Reinstalling what?

Linux mint and windows still work

So kparted wouldn't work?

I can install it in my usb too

[digital spade]

Partitions are formatted completely with a file system. Yours was formatted in an incomplete fashion. It is weird that it works at all. If it does work like that, do not touch it and continue to use the system. If it creates issues, back up all your data and reinstall both operating systems like you would on a new PC.

[obtuse glen]

Well i think it didn't change the 100mib fat32 partions. It just failed to add 200mib

[digital spade]

Either way, this cannot be fixed unless you are an expert on filesystems and partition structure, in which case you need to fix the partition table byte by byte. Have fun with that, I know nobody who can do that. This is a broken partition, and the fix is wiping it.

[obtuse glen]

ok :3

Last question do you know how to creat* not change a fat32 partions with a specific UEID

[digital spade]

I know that you cannot. As to why, feel free to study what a UUID actually is: https://en.wikipedia.org/wiki/Universally_unique_identifier

[obtuse glen]

@digital spade i can't believe it i found someone who had the same issues as me

All long help threads should have a sticky globally-editable post at the top saying 'DEAR PEOPLE FROM THE FUTURE: Here's what we've figured out so far ...'

[obtuse glen]

Actually i found an answer

[digital spade]

Congratulations.

[obtuse glen]

I'll let you know if it worked.

Asked 6 year 9 month ago is crazy

[obtuse glen]

@digital spade so i found a way to create a new fat32 sda1 with a specific uuid ( i used the old one as you can see)

It's because fat32 apparently don't use uuid. It uses some medata used as uuid

[digital spade]

Feel free to share the link to that solution and rename the thread with the actual topic, then it will help other people in the future.

[obtuse glen]

I need to rename the flags too?

[obtuse glen]

I'll create a thread with the solution

[digital spade]

Just make it something more useful than "My thread".

[obtuse glen]

It did work. I'll write the complet steps i followed now @digital spade

Linux Dual-Boot Fixing the EFI FAT32 UUID

Useful links: https://superuser.com/questions/1247972/how-to-change-vfat-partition-uuid

This issue is related to GParted

I used a command to copy my files in the sda1 into a backup folder

Then formated it into ext4 and back to fat32

Then used
sudo mkdosfs -F 32 /dev/sda1

Sudo mkdosfs -i put the UUID /dev/sda1

remember mkdosfs will format the fat partition and give it the specific UUID it does not change the UUID. If you want to change it follow the steps in the useful link provided

Then i added the flags boot, esp

And that's how i resolved the issue

[frosty jasper]

does it boot fine now?

[obtuse glen]

Yeah both win and lm

[frosty jasper]

if so, good on you

yeah dont mess with the boot partition any further. it's extremely vital
