[SOLVED] dual boot LMDE 4 & Win 10 disk error issue

#1 Post by pdm »

stumbled on answer at https://bbs.archlinux.org/viewtopic.php?id=239157 - the Ext2Fsd 0.68 utility installed on Win 10 (although no longer used, must be active in the background) was causing the issue. Confirmed by uninstalling it ... it only affected the LMDE 4 partition, not the Mint 20.1 partition.

As background, have been dual booting Linux Mint (currently 20.1 - a much appreciated OS) and Windows (currently Win 10) for five years or so without any boot issues. I have a separate NTFS partition for my personal data, which is shared by the respective OS s...

Recently decided to try out LMDE 4 as a possible replacement for Mint 20.1, which is starting to have some speed issues, and find it well suited to my needs and faster than Mint 20.1 (particularly with regard to Libre Office, which is annoyingly slow opening in 20.1) - so at the moment have three OS s installed...

The LMDE 4 issue is: for some reason, booting into Windows introduces disk errors into the LMDE disk partition, which prevents booting into the LMDE OS & instead end up with an initramfs prompt... to fix either have to run "fsck /dev/sda# -y" at the prompt (a very lengthy process) & reboot or boot into Mint 20.1 & use Gparted to check & fix errors on the LMDE 4 (ext4) partition & then reboot into LMDE 4.

I thought it might have something to do with the EFI (fat32) partition installed as part of LMDE 4 but temporarily deleting it made no difference.

Any suggestions, short of getting rid of Win 10 - which is generally used once per month to keep it updated & to make Macrium Reflect backup images (a 3 to 5 min. process) of the Linux partitions, etc., would be appreciated...

LMDE might have been derived from Debian, but it is no longer Debian.

Perhaps you should ask on the LMDE forum https://forums.linuxmint.com/viewforum. ... 3b586e4248

Windows is not supposed to mess with ext4 filesystems. What is the exact error message ?

Using gparted for this is a huge overkill.

No, the initramfs does not care about EFI partitions.
What is the output of fdisk -l ?
