Comment 7 for bug 125730

It was a fresh install on a different machine than before.

When setting up partitions during the installation, I chose to use the preexisting FAT32 Windows partition as vfat, to be mounted on /windows. Installer put it in fstab, with "1" in the sixth field, causing it to be fscked (with the same priority?) as root partition. If fsck finds errors on vfat partition, Ubuntu will remount root read-only and stop booting.
