Uhh...I want to try using 7.10 Beta, but it's being a pain and not working. I opened the partition editor, deleted my corrupted 7.04 partition and swap (leaving my Windows XP NTFS in place), opened Install, and set up...BUT it came up with the stupid migration assistant, saying something like "couldn't unmount /mnt/migrationassistant, and gives the options "Go Back" (which cancels the install, useless because you can't resume or anything) and "Continue" (which just leaves it stuck at 88% installing). I don't even want to migrate my documents to Ubuntu...I have tons of stuff there and don't need 2 copies of it, when I could just mount my partition. So, for now, 7.10 needs a lot of work, because it doesn't seem to install GRUB until after it's migrated, but it gets stuck, so I can't boot my PC using it.
EDIT:
They really need to put important options in the GUI...after hours of confusion, looking at the installer on command line came up with
sudo ubiquity --no-migration-assistant
Worked fine.
However, it's turning into the dreaded Windows...the EARLY days of the dreaded Windows...the Restart-your-computer-every-10-seconds days of Windows. Within a minute or so of working in it, it asked me to restart to apply changes (changed graphics to fglrx) then again to change RESOLUTION (which it couldn't figure out that my monitor is 1280x1024, not 1024x768, so I had to select it manually). If there's one thing Linux needs, it's a decent video system. The xorg.conf edit-everything-in-commandline feels ancient compared to the GUI of Windows. The X window systems need to get a solid GUI configuration that allows you to change everything without ever having to enter command line, and needs to autodetect information like max resolution from your monitor like Windows does. Also it bugs me about using fglrx, because it's restricted...if it wants to complain, why not provide a good driver for my graphics card? I honestly can't wait for ATi to release specs so that the open source ATi driver will support X series cards.
