Hi all.... My laptop was running fine till recently, when one day it wont boot up and gave a Blue Screen of Death with a UNMOUNTABLE_BOOT_VOLUME error... so after searching for this on the net, i found out that the hard disk might be corrupted... so i ran the chkdsk tool with the XP setup cd... the laptop wouldn't boot up even then.... so after some more searching, i used the fixboot tool of the XP cd and now my laptop boots, but... everytime i boot up, the laptop goes through the BIOS sequence, and show a black screen for about a minute... then it shows just a white progress bar at the bottom of a black screen (no XP logo).... this bar takes around 5 minutes ... it particularly takes a lot of time when it is around 15% and around 30% complete.... then the XP logo showsup with another progress bar and then the laptop boots properly... i dont know why this happens... i have searched like hell on the internet.... but haven't been able to find a appropriate solution... i have tried every suggestion on the net like defragmenting the hard disk, cleaning up the registry, chkdsk, but still no luck.... i dont think it is a physical hard disk error, because chkdsk shows that my hard disk is fine now... i really am desperate for some kind of a help, because it would be too much of a pain to do a fresh install of xp , since i have a lot of applications installed on my comp.... if u r reading till here, i really thank you for your patience 'cos i know the post is long, but i though it would be better to post the problem cleary so that someone could help me out.... pls,pls somebody help me.... thankyou john

I would suggest you to reformat it and start fresh!

hello you might try useing system file checker and run it. http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B310747 http://computing.net/windowsxp/wwwboard/forum/71865.html Name: LU89 Date: July 26, 2003 at 18:52:41 Pacific Subject: System icons Reply: Have you checked your files to find out if they are corrupted. Use the System File Checker tool to scan your computer: Click Start, and then click Run. In the Open box, type sfc /scannow and then click OK. you may be prompted to use the Windows XP installation disk. Note the space between the c and / have a nice day

I know it is a pain to rebuild a system but getting the UBV error and trying to correct it is a pain in the butt. I agree with Sam on starting fresh and this is why you make backups of important data and programs and keep them in a safe place. You can try the repair option in the XP setup and reinstall the OS but it normally does not work with the UBV error. KTTD

I am currently trying out sfc now... Before that i found that the white progress bar indicates the loading of drivers, because i included the sos mode in boot.ini... when restarted after putting in the sos mode, the drivers loaded very, very slowly .... after the drivers are all loaded, the rest of the boot process is normal... any more ideas.... and thanx for all ur suggestions till now... am keeping my fingers crossed, till the sfc completes... (oh i am not actually keeping my fingers crossed, 'cos i wouldn't be able to type this message then)...

sfc /scannow is complete... but still the computer boots slow

hi, do you have a restore disk that came with the laptop? If so I would suggest that you use it. also I had these errors and I bought a new hardrive cause the errors kept coming even after 3 clean installs. can you send this to the manufacturer of the laptop? I hope this helps. Gigz
