My computer has two systems, Windows 10 and ubuntu18.04. Today, when I tried to get into Ubuntu(I already laid it aside for about one week ), the whole screen showed pure purple for at least 10 minutes, so I forced the computer to shut down.Then when I tried to get into Ubuntu again, it showed :

Then I tried to open ubuntu in recovery mode,but the outcome was same.And I also tried this solution:https://forums.linuxmint.com/viewtopic.php?t=47594,doesn’t work either.
At last I run fsck.ext4 -y /dev/sda1(where the root is),and showed:

How to partition hard drive in Ubuntu 20.04

I’m literally brand-new to Linux and Ubuntu, so please forgive my ignorance and bear with me here. I purchased a Dell Inspiron 5593 recently and immediately installed Ubuntu 20.04 on it. Long story short, the keyboard is screwed up, and the place I bought it from won’t service Linux OS. Gotta be Windows/Mac OSX for some stupid reason.

So now I’m trying to partition the hard drive and reinstall Windows on the the partition. I’ve checked out GParted, but I haven’t been able to follow the documentation. For example, I don’t see any unallocated space on my disk, and I’m not willing to unmount my main disk without knowing what that will do to my computer.

Honestly at this point I’m ripping my hair out and would just appreciate some clear instructions on how to partition a hard drive in Ubuntu 20.04 because I’m clearly too technically illiterate to understand GParted’s documentation.

Ubuntu 20.04 Does Not Boot


Looks like this one just needs to have their GRUB re-written to MBR again. It’s not so hard. But given that I did something like this 8 years ago… The concept should still be the same. Steps of what I did to fix it here.

I originally had Ubuntu 18.04 installed on my dell xps 13 (2017). A couple days ago, I replaced it with Ubuntu 20.04 due to constant error messages. Until today, I was able to use it without any trouble.
However, I had to use Windows earlier today, and now when I was trying to boot Ubuntu back, I am unable to do so.

First error message

Unexpected return from initial read: Volume Corrupt buffersize 1000 Failed to load image EFIubuntugrubefi: Volume Corrupt start_image() returned Volume Corrupt

and then windows booted automatically.

In trying to resolve the issue,

  1. Tried reinstalling Ubuntu 20.04 using LiveUSB, but got the error saying the system doesn’t have EFI System Partition
  2. Consulted the forum https://ubuntu.forumming.com/question/5394/unexpected-return-from-initial-read-volume-corrupt.
    In running Boot Repair, I received an error message, sayin EFI System Partition is needed.
  3. Used GPart to try to tweak disk settings (changing the disk partition that holds Ubuntu File System from ext4 to fat32… I didn’t document this process very well)
  4. Followed a tutorial that used Windows command prompt and diskpart, creating an ESP.
  5. Reran Boot Repair (successfully this time)

However, now I encountered a GRUB error

“Minimal BASH like line editing is supported. For the first word, TAB lists possible command completions. anywhere else TAB lists possible device or file completions.”

I’ve been looking up different solutions, but I am having trouble understanding them, and afraid I am messing my disk more and more.

Thank you in advance.
