Quintin is most likely correct wrt Jan's problem. Looks like the machine is
trying to boot from the network and not finding anything - this would
happen before ubuntu even starts loading, and it would be a BIOS config
(re: bad disk)
I just want to add, speaking about slow boot problems, hardrives, and ntfs:
I've recently troubleshooted a slow boot due to a hard drive going bad;
additionally it had a separate NTFS partition on it also (shared with
previous win7 dual-boot) - I could see many read errors in the boot logs,
due to bad sectors.
(see boot logs by typing
$ dmesg | less
(makes output scrollable) - look for error messages containing strings like
"ata1.000" or "/dev/sda" etc)
(re: read-only ntfs)
Furthermore, /etc/fstab may have instructions for mounting the NTFS
/dev/disk/by-label/Media2 /media/Media2 ntfs-3g
rw,errors=remount-ro,users,sync,noatime 0 0
If there's an error mounting the ntfs partition, the "errors=remount-ro"
causes an attempt to remount the filesystem read-only when a read-write
I'm not sure if UDEV->gnome-vfs (?) has a similar remount-ro policy (i.e.
click-to-mount autodetected 'partitions' in nautilus)
