Error 2000-0142 I have a dell studio 1525 it won't boot up and I recieved the errors 2000-0142 and 0f00;0232. I don't have the disk so I can't boot from them. Any ideas

If you did not change the CPU the the BIOS is not seeing it correctly. You can update the BIOS or you should be able to press F1 to continue to boot.

NO BOOTABLE DEVICE When the PC cannot see a boot file/disk on either the hard disk or floppy drive it gives an error message "No bootable device. Insert boot disk and press any key"
There may be a hard disk problem.
Check the BIOS to see if the hard disk is detected, if not open the case and re-seat the hard drive and also where it connects to the motherboard.
If it still gives this error message and the BIOS does not detect this hard drive, then the hard drive is probably faulty.

To get the computer operating again, install a new hard drive in your computer and then install Windows on this hard drive plus the computer's device drivers and your programs.

your HDD may be corrupted, re-installing windows vista is one option. Your best bet is if you have/ can obtain a copy of windows vista run setup and try the repair wizard in the windows vista setup, the wizard automatically finds errors and missing files and replaces them therefore solving any errors in your HDD. you can also try to use the recovery wizard from your recovery disc. best of luck

This is an error code, if you get in touch with the manufacturer they will identify the error for you.

For that First when you power up the computer press F1 or F2 or "del" key to enter in bios .
Then go to boot option and set first boot device as your cd or dvd rom then save settings and exit.
Then it boot with your recovery disk.
Then follow the procedure and enter in recovery console mode.
Then type in prompt "chkdsk /r"
then press "y
then it fix error on harddisk.
Then check if still same error then again boot with disk then repair your windows .
Let me know if you need more assistance.
Thanks.

its bugged or so ...ir its missing files that were deleted by the anti-virus...
so ...format and reinstall ....be sure that ya format at least the C partition ....cause if ya have a recovery cd ..it will go under the last installation and the problem will reappear

Error Code 0146 refers to failure to find or load NTLDR files, needed to run your operating system. Place your Restore disk in the DVD drive, power up the computer, hold down the F12 key till boot screen shows up. Boot from DVD and run Repair to restore these files.

If you have error codes from the diagnostics, then your drive is failing or has already failed.

Check with Dell to see if you still have a warranty on it. It is covered, if your warranty is still in effect.

Booting to the CD requires that in the Boot Up (BIOS) that you have selected the CD as a bootable item - and that there is something to boot TO in the drive...

Get a bootable Install CD for whatever version of Windows and re-install windows from the CD drive. (Windows XP Home I imagine). If the laptop won;t boot from a CD you can alter the BIOS settings to allow it. If you don;t care about your documents, do a DESTRUCTIVE install which will wipe your Hard Disk.  Beware if you do a non-destructive install  that if your problems originated from a virus it could still be on your Hard Disk. If you need help with getting the BIOS  settings changed lemme know.

Try check your hard disk with the other machine. Try running hard disk diagnostic test. If there's a problem with diagnostic test i suspect your hard disk is faulty. If you tried connecting with other machine then same problem, suspected also hard disk faulty. You might need to change it.
