[App_rpt-users] e2fsck..... halted during boot

(ala Mythbusters)  "Well *THERE's* your problem!!"

Try the VIA release rather then the i686.

That format is only on the optical disc (or local loopback of the image file if you install that way). Typical thumb-drive images I've seen have a small FAT filesystem that boots and mounts the install iso image as lookback. The installer, as part of system setup/install formats the local storage device (typically /dev/hda or /dev/sda) in a Linux file format. These days either EXT2 (non-journaled) or EXT3/4 for journaling. This has no relation to the install media!

This is the same as typing in "linux 1" on the grub boot line (or LILO on old distro's). The point is to leave the main system disks unmounted and allow you to repair them. Typically just running fsck will repair them. You will need to do this for each partition (logical or physical) that has a problem. It will typically prompt you about problems it finds - pay attention as fsck runs - you might have to answer "yes" many times! Might be good idea to run fsck on all filesystems while your in there. Afterwords, when you type "exit" from the single-user shell, the system will automatically reboot - and if all is well will boot back to Runlevel 3 or 5 depending on your init setup with your repaired filesystems mounted properly. This is full multi-user/normal mode of operation your used to

Most distro's install disks offer a "rescue mode"... so just download/burn a current copy of Fedora/CentOS/etc and you can use them as a rescue tool - and don't need to even have that same distro installed! Just look at the install menu and see if they offer a rescue mode. Typically you just type "rescue" and hit enter. It will then load up a minimal system into a ramdisk with most drivers installed that will detect your disk controller and other devices. When it asks if you want to have it mount filesystems answer "N". Then once it drops you to a shell start "fsck.ext2 /dev/hda1"/etc on EACH of your filesystems.
