BleepingComputer.com: Cannot get into my PC after Comodo CIS update

My PC is an AMD Athlon 2400+ with 1GB of RAM. The OS is Windows XP Home Edition SP3 and kept up to date with windows updates. I use Comodo CIS 3.8 updated to the latest version the latest version. I also have Comodo Boclean and Spywareblaster as realtime protection and use SAS and MBAM as on demand scaners. I scanned my PC with the CIS AV and SAS and MBAM over the last few days and my PC is definitely clean. This morning I checked my Comodo CIS for updates and was told an update was available. I let it download and install and when I clicked on Finish I noticed that the CIS icon in my task bar disappeared. Instead of trying to restart it from Start> All Programs list iI rebooted my PC which then crashed just before the Windows Enter screen. When it rebooted again the screen with Start normally/Safe Mode/Last Known good config came up. I have tried each of the 5 options on this page several times and cannot get the Pc to boot it comes to that page every time.
I decided to reformat but although I can get into BIOS and put the Windows disc in the drive Ias soon as I switch off and restart the PC it returns me to the other screen. Can anyone tell me if there is a way into my PCV through the BIOS to uninstall or disable Comodo.
Thanks for any help.

Have you tried running chkdsk /r (from the XP Recovery Console) on the boot/system partition?

Go in the BIOS & locate the Boot priority.
Se it to boot from the CD drive first.
When you put the disk in the drive & start the computer watch the screen for a message "Press any key to boot from CD"
Press a key.

If you aren't familure with reinstalling XP at a certain point during the install the computer will restart.
Don't press a key to boot from CD !
Let it restart on it's own & the installation will continue.

You can't disable software in the BIOS.

You might try using the Recover Console before doing a full reinstall.
When the XP disk first boots watch for ,"To run the Recovery Console Press R"
When you get to the prompt type in: fixboot & press enter
You will be asked if you're sure to wriye a new boot file ,press y .then enter.
When you are back to the prompt type in : fixmbr , you'll get a prompt asking if you're sure, press Y then enter.

If that works it will save you from having to reinstall everything .
