I typed everything below and then noted that you can't boot from a CD. Are you sure that you used the proper procedure to boot from the CD? If not, let us know the make and model of your system and we'll suggest some ways to test this.
Failure to boot from the CD (in addition to failure to boot from the hard drive) says (to me) that there's something going on at a lower level on your system that I'd previously thought. So, the first step would (IMO) be to disconnect anything that's connected to the PC (leave the monitor, power, keyboard, and mouse connected). Next would be to reset your BIOS to default values - for this type of error, I prefer removing the power and the CMOS battery and leaving them out overnight.
Once you post back about the CD boot situation, then we can move on with trying to fix this. I've left the stuff that I typed previously just in case it's needed later on (it's the strikeout stuff that follows).
I've searched all over for a solution to this, and the results aren't very helpful. The best search was when I searched Google for "y8y8" (without the quotes). Most of the posts there presume that this is a virus and probably is a boot sector virus - but that's not a definite answer.
BTW the ∞ symbol is done by holding down the "Alt" key and typing 236 on your numeric keypad (at least on my system).
The first suggestion is to run a bootable diagnostic utility from the manufacturer of your hard drive. That'll let you know if the drive is physically OK.
Then there's various tools to attempt to fix your boot sector (the most commonly used being the Windows Recovery Console): http://www.bleepingcomputer.com/tutorials/how-to-install-the-windows-xp-recovery-console/
Unfortunately, most attempts of this type met with failure
There wasn't much reported about slaving the drive to another system and scanning it there to remove the virus.
Another thing that was discussed was "ghosting" the hard drive with Norton Ghost and then re-installing the image. There's no sound reason for this working - but at least one person reported that it worked for them.
Unfortunately, the only sure cure that I noted was a "low-level" format of the hard drive and a clean install of Windows.
If you'd like to go with the low-level format and reinstall (and maybe attempt to backup your data) - please PM a mod to have this moved to the XP forum.
PS - have you tried resetting your BIOS to default values? It's just a shot in the dark, but whatever's causing this could also be associated with the BIOS if their programmers put this code in.
