It might be cause by The MBR was messed up by a bad grub install. You can try to fix the grub.

If you want to try reinstalling grub, boot from the live CD, log in as root, open a Konsole window, and at the prompt, ([root@localhost ~]#) type;

[root@localhost ~]# grub <Enter>

GNU GRUB version 0.97 (640K lower / 3072K upper memory) <-- This is the output from grub after <Enter>

[ Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists the possible
completions of a device/filename. ]

grub> <-- The grub prompt.

From the grub prompt type;

grub> find /boot/grub/stage2 <Enter>
(hd0,0)
(hd0,4)
(hd0,5)
(hd0,9)
(hd0,11) <-- You'll only have one, use it
(hd1,0)
(hd1,2)
(hd1,4)

grub> root (hd0,5) <Enter> <-- Use what showed up above for yours
Filesystem type is ext2fs, partition type 0x83 <-- Grub reports both ext2 and ext3 as ext2. Don't worry about it.

grub> setup (hd0) <Enter> <-- That is a zero (hd0), not a letter
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+15 p (hd0,5)/boot/grub/stage2 /boot/grub/menu.lst"... succeeded
Done.

grub> quit <Enter>

Your done; grub is reinstalled

My computer keeps rebooting


Does it Boot or is it stuck in a boot loop cycle? Have you done ANY hardware or software, new OS?, updates/upgrades lately? Memory? Put in a new CMOS battery. Try reseating Memory Mods. Are the Fans, heatsink, vents clean? Open the BIOS setup, check Clock, set if necessary, Disable Auto Reboot. Remove ALL Media DVD,CD,USB devices, Printer cable, ect., Will it boot to Safe Mode? Take a look : http://searchenterprisedesktop.techtarget.com/Steps-for-solving-the-reboot-loop-problem May be a bad HDD? Remove and test, replace if necessary.

Need a boot disc for my 2005 desktop I wiped the hard drive with SecurErase, when I tried to reboot only COMPAC comes up on the screen.


If you have wiped the HDD then it no longer has an OS installed and you would need to purchase one if you wanted to use Windows (whatever flavour).

You can however use a Linux system which is free. There are several different versions of Linux but I recommend you try this one

I want to reboot my asus eee pc 900 and i dont have the disc. i was wondering if i could download the reboot somewhere and use a usb to reboot it.


Yes you can - I a m not sure where you can get the original OS for that model, however installing an OS on that model using a bootable USB is possible. Use this link to find instructions on how to for Windows OS's -
http://www.serbanghita.com/install-windows-xp-on-asus-eeepc.html
If I am not mistaken, the original OS on the Asus is a Linux OS which I think will require you to use a program called unetbootin to make the bootable USB. Use this link for unetbootin http://unetbootin.net/
You can also perform the same task using an external hard drive.
Hope this answers your question and helps FixYa! let me know if you have any other questions? Meanwhile, share the love and leave me some feedback!
