dimegrind Posted July 22, 2004 Share Posted July 22, 2004 If you have any important files I would back up your machine before you do anything else.Did you ever run the Upgrade Advisor from the cd or the microsoft website?You should have ran that first, it will tell you wheather or not your system is ready to upgrade to XP Pro. If it is not it will list the software/hardware that needs to be updated and will retrive those updates for you (most of them).If you still have errors occuring your best bet is to format and install fresh.

indianarchie Posted July 23, 2004 Author Share Posted July 23, 2004 yeah..i had run the upgrade advisor the first time i installed xp...i carried out the steps given there. however i dont think i need to run it the second time(when install failed) coz i havnt made any changes in my system apart from removing norton antivirus. could u tell me if it is necessary to do so? also , i dont want to take a risk of losing files by doing a clean install....who knows if midway thru the install, there might be an error..can i safely go back to my prev OS without losing anything?pleses guide me on this..i hav been getting frequent crahes on win ME (which im using) ...i want to upgrade to XP soon as possible!and all of you who posted ur replies...thanks a ton for your help!

likuidkewl Posted July 23, 2004 Share Posted July 23, 2004 Take your important files and back them up to a cd or another patition/HDD. Then do a clean install, I honestly have never heard of anyone upgrading the same installation twice. I am not suprised by the errors. Link to comment Share on other sites More sharing options...
