I just installed Ubuntu 11.04 over an older version of Ubuntu, and am dual-booting with Windows 7. Most things seem to be working well (i.e. wifi, sound, etc.) but boot time is problematically long. After choosing 11.04 from grub 1.99, I get the purple screen for several minutes before the Ubuntu log-in finally appears.
According to dmesg log, the delay seems to be related to mounting the file system:
... [ 28.989223] EXT4-fs (sda5): mounted filesystem with ordered data mode. Opts: (null) [ 305.166041] Adding 3178492k swap on /dev/sda6.

Any help would be appreciated as I am rather new at this and would really like to move to linux. Thanks, and sorry in advance if the answer is really obvious!!

Sadly, reinstalling ureadahead has not decreased the time.
Best Answer
I saw some problems with the same a year or so back.
Do you have a file named
/var/lib/ureadahead/pack?If so, delete it with
sudo rm /var/lib/ureadahead/packand then do a reboot (this will force a rebuild of the pack file used by ureadahead).After a couple of reboots some have reported to work and some claim the problem came back.
If the latter remove and (re)install ureadahead. You can do that from USC:
