A friend was given a computer as a gift, however it is stuck in a blue screen loop the error code is
Stop 0x000000ED (0x8278BBB8,0xc00000060 the second string of numbers changes at last try they were 0x827DDb20). I've tried to boot in safe mode and get the same error. Microsoft says to rerun the window xp cd and then run chkdsk/r. I however cannot get this machine to boot from the cd rom (says the drive is not bootable) and my friend does not have a windows boot disk.

PS. where can I download a boot cd in cd rom format, none of my pc's have floppy drives.

as always any help would be greatly appreciated.

Stop 0x000000ED or UNMOUNTABLE_BOOT_VOLUME

The kernel mode I/O subsystem attempted to mount the boot volume and it failed. This error might also occur
during an upgrade to Windows XP Professional on systems that use higher throughput ATA disks or controllers
with incorrect cabling. In some cases, your system might appear to work normally after you restart.

Possible Resolutions:

• If using higher throughput ATA disks and controllers, those capable of data transfer rates above 33.3 megabytes
per second, replace the standard 40-pin cable with an 80-pin cable. Using an 80-pin cable is optional for
transfer rates up to and including 33.3 megabytes per second, but is mandatory for higher transfer rates. The
additional grounded pins are required to avoid data loss.

• Some firmware enables you to force higher transfer rates even when you are using the incorrect cable type.
Your firmware might issue a warning but allow the startup process to proceed. Restore the default firmware
setting for ATA cable detection.

• Problems that cause 0xED errors might also cause Stop 0x7B errors. For more information about 0x7B Stop
messages, see "Stop 0x0000007B or INACCESSIBLE_BOOT_DEVICE" earlier in this appendix.

cannot get this machine to boot from the cd rom (says the drive is not bootable)

That maybe be a message about your hard drive, not CD drive.
What Windows CD is it, you try to boot with?
When you restart computer with the CD in, do you see this message?
Press any key to boot from CD
If not, you may have to access BIOS and change boot order.

I have a windows xp installation cd, I've gone into bios and they are already set to boot from the cd rom drive yet the system still boots from the Hard drive. I assume that it's not accessing the cd and going to the hardrive. I don't have a boot cd and the only ones I can find online are made to be used with floppy drives. This pc has no floppy so I need to find a boot disk on a cd.

I have a windows xp installation cd

Is it full version XP CD, or some restoration CD?

[Steve DeVore]

It's a full version

[Broni]

Just to eliminate bad CD, create another bootable one...

Download Windows Recovery Console: http://www.thecomput...om/files/rc.iso
Download, and install free Imgburn: http://www.imgburn.c...hp?act=download
Using Imgburn, burn rc.iso to a CD.
Boot to the CD...let it finish loading.

Original Genuine or burned copy of XP?

[Steve DeVore]

burned copy

[rshaffer61]

There's your problem.
Where is your original Genuine OS disk?
Burned copies rarely work because files do not always burn correctly.
Where did the copy come from?

[Steve DeVore]

Received it from a friend, I guess he did not want to let go of his original copy
