I know my problem sounds pretty common but all advices I found on the internet did not worked for me.
I try to resize partition and I cant lower its size.My previous SSD disk failed and I need to install system on my second HDD disk. HDD was previously formated on win7. I could create new partition instead of old but obviously I want to keep my data untouched. During Ubuntu installation proccess partition manager says its unallocated space but its normally booting to view folders and stuff.
I experience error like:
In this case /dev/sdb/ is linux pendrive but I think it might be related to /dev/sda/ - HDD. I tried to fix this with doing:
- Changing Boot mode from UEFI to normal mode.
- Using gparted (error above) with result red exclamation mark near disk.
- Using fixparts on my HDD (/dev/sda/) with result:
Loading MBR data from /dev/sda
This disk appears to be a GPT disk. Use GNU Parted or GPT fdisk on it!
Using testdisk which wrote MBR to partition (on /dev/sda/)
Using gdisk on /dev/sda/ with commands: x then p then w. Gdisk told its valid GPT table.
Tried to change in my UEFI storage setting AHCI to IDE.
I know my approach is chaotic, as I just try different internet solutions. Maybe there is something wrong in order of things I did.
