However, you will be able to test all your hardware without touching your disk. Just one thing to remember: since everything is loaded from the CDROM, everything is much slower than it could be expected when booting from a hard disk. This mode will let you test your hardware for compatibility, for example. When you boot the CD, you can start Ubuntu Linux in LIVE mode. Specific info on Ubuntu's Live CDs is available here:īoth are the same.
It then allows you to install fully to the HDD if required.
The article ends, "For now, if you're running Ubuntu 20.10 then the best thing to do is keep using it and wait for Canonical to give the all clear, or for the upgrade notification to appear.A Live CD allows you to boot the full OS from the CD and try it out fully without affecting your existing HDD OS installation. Over at PC Magazine is and article dated April 27, 20021, titled Upgrading to Ubuntu 21.04 Is Not a Good Idea Right Now. I may have just stumbled on the cause of the problem, although I would think I would see more posts about people unable to boot the Live CD. I did, however, download another copy of the. No, I didn't verify the download - I don't have gpg on my Windows 7 desktop, and that's what I was using to download. Then I wanted to try the newly released 21.04, Hirsute Hippo. I was able to boot up both the 20.04 LTS and the 20.10 drives.
I was referring to booting Ubuntu from USB and updating, in the same way I would update an Ubuntu install on my hard drive.
I expect eventually using Windows 7 will become untenable, but for now I have a couple of games that I can't run in Wine and won't run on Windows 10 (which I utterly detest anyway). The procedure is explained at How do I Install an Entire Ubuntu on a USB Flash Drive?. I don't have enough space on my hard drive for a satisfactory dual install, so this is perfect for me, especially since 64GB flash drives became affordable. I've been doing this for several years now, and don't remember why I found this method better than "persistent" live USB installations. I do this by installing the distribution on a USB 3.0 flash drive. From time to time I browse Linux distributions. Last edited by Acharn May 1st, 2021 at 11:57 AM. Oh, the motherboard is seven years old, so the EFI might be a problem according to a post I saw about Kubuntu. I thought about downloading the 21.10 daily, but the browser says it would take three hours, so I don't want to go there yet. I'm not including much info about my system because I don't know what might be useful, but I will give it if wanted. I haven't seen any other posts saying the live CD failed to boot, so I don't know what to do next. I had a problem a few years ago when a change to X had an obscure bug that only seemed to affect this particular CPU, but then the screen just went blank, and Ubuntu fixed the problem two releases later. The first item was in red and said " unmounting /cdrom." Then it showed about 25 entries, all preceded by "" and stopped for about another minute and displayed, " Failed to start Ubuntu live CD installer Service.el crash signatures." At 5:00 minutes that went away and I got a checklist. That lasted for 4:00 minutes, then the screen went blank and then came back without the rotating thingy. When I tried to boot, I selected Ubuntu from the menu and after a minute or so my screen was showing the motherboard's logo, the rotating thingy, and the name Ubuntu.
The procedure is pretty easy, except the Ubuntu installer requires setting up two partitions, one for the BIOS boot loader and one the EFI data, and doesn't tell you how large they must be to work. I just finished updating the 20.04 LTS installation and the 20.10 installation. I've installed several Ubuntu versions on USB digital drives to experiment.
