I have a laptop hp compaq presssrio CQ57-447EI that recently failed to startup after i tried to down load microsoft office 2007. The download was ok then then screen showed like its in hibernation, with all lights on.Tried to touch the touchpad but could not respond.Then did a force shutdown but then it failed to startup. It then showed the startup repair, which failed to repair it.I tried to boot from the installation DVD ,then used bootrec.exe /FixMbr
All the above commands said the operation was succesfull but still they could boot the laptop.
Then also tried to the following commands ;
bcdedit /export C:\BCD_Backup
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
it showed operation succcesfull,but still it couldn't boot but brought up an old account.
Then tried to install an other operating system it . It installd but i dont ve the product key, and i cant access the data in the failed account.
After several attempts to repair the bootsect it 's now show the following:
windows failed to start. A recent hardware or software change might be the cause.To fix the problem:
1.Insert your windows installation disc and restart your computer.
2.Choose your repair language settings and then click "Next"
3.Click "repair your computer."
If you dont have this disc contact your system administrator or computer manufacturer for assistance.
Info: windows failed to load because a required file is missing, or corrupt.
All my efforts have proved futile kindly help me out.Thanks in advance.
