As such I do not know which is my CD/DVD drive .

I've already taken a copy from another computer on a pen drive . But how do I install it on the troubled PC . help me out .

I am thankful to you for replying to this problem . Your the first and the only one to do so . I am a Sony Vaio TX37GP user . This notebook does not come with any recovery disk or the windows installation disc . As a result of which I am only able to burn a bootable disk of i386 folder from another computer and boot from it then a Caldera DR-DOS 7.03 pops up . I do not know what to do . My pc  is now off for quite a lot of time now due to this outcome . 
Please guide me likewise . Thanks .

I'm a new diskeeper user and had defragmented my drives (C:\ and D:\) for the first time yesterday . Thereafter I restarted my computer as it asked me to do after installing Windows Update . Now, when it powers on during restart it does not start at all . Instead it gives a warning that the 'ntoskrnl.exe' file is either corrupt or missing and advices me to install another copy of the file . Now that I have the file with me I need it to start atleast once so I can copy it in the system32 folder . Please help me .


PS: I have already tried out all the options on 'F8' during startup , but to no avail .

Thank you very much  for your reply . But as th driver came installed with the computer directly from Sony and I do not have the drivers required . The device manager dos not provide me with the option to delete the drive . It only allows me to uninstall it . As such my hands are tied . I hope you can help . Thank you in advance  .

I would be extremely thankful to anyone who could help me out . Since a particular period my CD/DVD drive has not been functional . I mean I cannot find it in My Computer and I am unable to open the disc tray as well . I have to insert a paper clip point into the whole in front of the disc . I checked it in the Device Manager and in device properties .
this message appears in the device status :

'Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

Click Troubleshoot to start the troubleshooter for this device.'

Mine is a #Word Censored#a UJ-832D .
please help me as the software engineer being an authorized person from SONY India recommends me to send the laptop to SONY for each and every small trouble . They charge me for it . anyone please help  .
