Can't boot because of Full Disc

md flag

I am running Ubuntu 20.10 LTS on a dual boot with Windows 10.

The other day I had the wonderful idea to run a data recovery utility... Long story short is I filled up my hard drive and now Ubuntu won't start.

  • When booting into Ubuntu, I get some error akin to "Community MySQL won't start". Researching that alluded to issues about not enough disk space, and since I recently filled up my hard drive, I'm guessing MySql doesn't start due to a full disk.

  • Booting into windows, I cannot give my Linux partition more space.

  • I can boot into GRUB, although I can't find much use for it. Doing the "Clean" option doesn't seem to do anything. I have two kernels available - 5-8.53 and 5-8.55.

  • My last idea before posting this question is to create a boot disk. I created a boot disk for 20.10, but that doesn't seem to work... Do I need to use a different distro than what I have currently?

  • I believe I do not have a boot partition. This is my first linux box, and i didn't know what a boot partition was until 10 minutes ago.

I just need to delete one folder from my Linux partition. What is the easiest way to do that without booting into the OS? Please and thank you.

What happened with your USB 20.10? That should boot regardless of your full Linux partition. Then mount your full partition, and delete what you need to. Don't confuse a /boot partition with an EFI partition, they are different things, and a Boot partition is only needed these days for special cases like maybe raid or lvm/encryption on your root.

I encountered an "id10T"error - I forgot I needed to press F10 to do the USB boot

I solved it!!

First, I forgot I needed to press F10 (or F-12 on some machines) to access the USB Boot thing.

Once I figured out how to correctly boot from USB, I was able to figure out how to delete files by following the instructions here.

The only caveat to those instructions is to prefix the fdisk and rm commands with sudo

If you get into trouble with your installed Linux ( Or windows ) OS, you can use the non persistent USB Ubuntu live installer to fix what you need to fix.

However, the OS partition can't be encrypted for a direct hard disk mount.

It is even possible to install Linux on to a USB in order to get a portable OS.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
