Windows 10 Pro on my old
ThinkPad R60 and shrank the
NTFS partition to
50% to make space for a dual boot Linux installation. Then I installed
Linux Mint Debian Edition 3, creating separate
EXT4 root and home partitions with GParted in the process, and having
Grub2 installed into
/dev/sda1 which is the boot partition for both OS. After installation, I booted into the new Linux and found that I cannot log in ("Invalid password, please try again"). I'm positive that I typed in the credentials correctly, I also reinstalled Linux twice using different credentials, but the problem persists. What might be the issue here?
