I keep getting an error when trying to install Ubuntu 10.10 on Windows 7. I insert the cd and then restart the computer. Everything looks like its loading great, but it gets stuck on the loading screen. So I pressed Esc, and it shows the following errors:

(process: 314): GLib-WARNING **: getpwuid_(r): failed due to unknown user id (0)

/init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found /init: line 7: can't open /dev/sdb: No medium found

I have also tried the check disc for defects options, but that also gets stuck on the loading screen. What am I missing? Has anybody else encountered this problem?

sdb is not a CD/DVD but an HD.

Oh, ok. So am I suppose to install this from a hard drive? – Amy Nov 29 '10 at 18:28
    
No. The point we are getting at is that you say you have an HD connected and a CD. This sdb thing is a second HD. Is it an HD? a thumbdrive? update your question plz – RobotHumans Nov 29 '10 at 18:30
    
That's strange. I only have one HD which is my internal c:/ drive where windows is installed. I don't have another HD. – Amy Nov 29 '10 at 18:36
    
it is odd, are you sure you don't have a second usb device of any kind connected? sometimes weirdness ensues becuase (for compatibility) some devices expose their storage as an HD – RobotHumans Nov 29 '10 at 18:37
    
I sometimes connect an external hd or thumbdrive, but they are not connected at the moment. – Amy Nov 29 '10 at 18:46
