Trying to install Linux Mint to dual-boot with Windows 11 I always get the above error. I`m not sure what is wrong, drive works perfectly on Windows and when I format it to ntfs, fat32, ext2, etc... it works perfectly as well. I cannot mount it either. The device I want to install it to is /dev/sda, a SSD of 250gb and my installation device is a 16gb pen-drive.

fdisk -l yields:

After doing mkdir.ext4 on /dev/sda:

I thought this would have fixed it but now it gave me

    root@mint:/home/mint# gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.8

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.

Warning! One or more CRCs don't match. You should repair the disk!
Main header: OK
Backup header: ERROR
Main partition table: OK
Backup partition table: OK

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: damaged

Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
  • Welcome to the community. The last line looks like you were intending to give more info? If yes, you can Edit your post to add the rest. Feb 8 at 0:00
  • Oh well, i've tried a couple more times to no avail. I'll log-in tomorrow and post some edits, sorry... Feb 8 at 1:10
  • As usual, when dual-booting with Windows disabling its Fast Startup feature is a must. So, start by doing that and shutting down Windows properly to make the setting stick. Then keep in mind you don't need and almost never there's a reason for more than one ESP (EFI System Partition); this mistake is visible on the results. When you don't know exactly what you're doing it's better to start with clean GPT drive (or enough unnalocated space if installing in the same drive) and use the automatic installation. Feb 8 at 13:45
  • Where can i disable that? I disabled secure boot on bios settings but that didnt change anything. I tried formatting the disk on windows but that didnt work either. Is there some way to clean the drive completely? I dont mind losing data (theres nothing in it). Feb 8 at 15:11
  • Also, heres another example of the error= (The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition #2 (sda) at / failed. You may resume partitioning from the partitioning menu.) Feb 8 at 15:13

By running mkfs.ext4 /dev/sda you created a filesystem on the disk, not on your target partition. You might want to start from scratch by creating a new empty GUID partition table on dev/sda:

  • Run gdisk /dev/sda
  • press o to create a new empty GUID partition table
  • press w to write the changes to the disk

The Mint installer should detect your empty disk and allow you to create and format the necessary partitions.

  • Should i format the disk first? Gparted seems to corrupt it when creating the ext4 file system. Also, i had the same problem trying that... Feb 8 at 15:53
  • You can create the partitions beforehand (if you like gparted more) and then select the partitions in the installer, but that's not necessary.

  • Did not work, it seems the GPT table becomes corrupted after trying to install, gdisk (before installation) says its fine but after it says its damaged. Feb 8 at 15:58
  • It says SD/MMC/MS PRO in your fdisk output. It could be that the card is corrupted. Do you have a spare card to test?

  • Well, i did try another sd card but it gives the same problem, and if it was corrupted it wouldnt work on windows right? Feb 8 at 16:04
