|You probably didn't need to try re-loading Windows regarding that error.|
You should never try to re-load Windows when you're not sure whether your computer is working properly. This particular error can be caused by a hardware problem - if that's your case you have to fix the hardware problem BEFORE running Setup.
You probably cannot get to Safe mode anymore because Windows has probably only been partially re-loaded. Windows is probably not all there anymore.
Assuming you DID NOT change which ram you have installed just before or since getting this error....
You can get the IRQL_NOT_LESS_OR_EQUAL error from many causes, but sometimes it can be just because the ram module contacts are not getting a good connection - this worked for me when I got that error:
(If you get that error during Setup it can't be caused by some software problem in Windows - it's probably caused by a poor ram connection)
A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, you must remove both its main battery and AC adapter before you do that.
If you DID change which ram you have installed just before or since getting this error, not all ram that you might think would be compatible with your mboard is compatible, and you can have memory errors because of that - if you still have the ram that was in it that it worked fine with previously, try installing only that ram.
" I began to run the re-install when at one point the disc had to restart my computer to further the installation. "
Windows XP Setup run from a regular Windows CD restarts the computer twice (or 3 times?) . If Setup encounters no problems, you should have seen a message "Setup" or "Windows will reboot the computer in 15 seconds" or similart at the end of each stage. If you didn't see that, and the same stage of Setup starts over again, that stage of Setup did not complete successfully. If you DID see that, you DO NOT press the key while booting to boot from the CD again - that starts Setup from the beginning again.
You should not get ANY blue screens before Windows Setup has finished, or afterward - if you do you probably have a hardware problem, such as a problem reading the ram, or your hard drive could be starting to fail.
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
If the hard drive tests ok......
If you get ANY errors saying Setup cannot read a file on the Windows CD, if you haven't changed which ram you have installed, if your Windows CD is an original CD, you probably have a minor problem with reading the ram - try re-seating it, cleaning it's contacts - or a problem with reading the the CD - try cleaning the CD, and cleaning the laser lens with a laser lens cleaning CD, or if this is a laptop you should be able to clean the laser lens manually when the tray is ejected without a CD on it.
If your Windows CD is a copy, a burned disk other than a CD-R may not read properly in a drive it was not made in.
