Thank you very much... the bootrec command worked!!!

Hi,

Error code = 0x490 - No OS found on the disk

---

Can you get to a Command Prompt?

---

Run: Drive:\boot\Bootsect.exe /NT60 All

or, Try booting with the disk.

Do not install, go to Command Prompt

Type:  fdisk/mbr

This will repair MBR

Another solution -

Boot configuration is corrupt.

Hi,

Check the cabling and power leads to the hard drive.

See if these help - boot with a Windows disk (repair disk ok) and issue these from the Command

Prompt and hit ENTER after each.

C:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

==========================================================

If the above did not help : (Be sure to check the cabling and power leads to the drive.)

Use the Advanced Methods, the Manufacturer's Diagnostic Utilities, and even the Trial Versions to thoroughly check the hard drive integrity.

Disk issues can get serious very quickly so I would thoroughly check the drive now and be sure

to keep redundant backups of your important data (use several methods).

Inside Windows - Regular or Safe Mode (repeatedly tap F8 as you boot).

Run checkdisk - schedule it to run at next start and then Apply OK your way out then restart.

For even better and more efficient checking :  <- Advanced Methods.

From the Command Prompt of the Recovery Console (if you have one) or from a Vista/Windows

7 disk - if you do not have a Vista/Windows 7 disk you can borrow a friend's (it needs to be same

32 or 64 bit and they are not copy protected) or make one. Also your System maker will sell the

physical disks cheap since you already own Windows.

Go into Setup/Settings (BIOS/CMOS) often F2 as you boot so watch screen as you startup. Set the

boot order to CD/DVD to use Windows disks (Vista or Windows 7 whichever you have installed.)

Remember to set back when done.

**If you need to make repair disks - these help repair Windows not re-install.**Often a these disks will help when the OEM Recovery Disk does not.

Download Windows 7 System Recovery Discs - now charging $9.75 for the ISO

images to make the disks. (These can be made on any computer running XP,

Vista, or Window 7 that has a CD/DVD burner.)
