boot into dos

Specs: Windows xp, core2 duo/4gb
my computer gives me the 0x0000007B error when i try to boot.[all parts of computer are new except hard drive] I understand that this error can (possibly) be fixed by entering dos and then typing in chkdsk. although, since i backed up the hard drive before i installed it in this new computer, i wouldn't mind formating it. the reason i offer that alternative is i have no disk or floppy drive from which i could stick a boot cd into, so can i boot dos from a flashdrive or what. if not, then how do i format it.

So you built this computer but did not include either a CD-ROM or Floppy drive?

Short answer is you cannot take a hard-drive with XP installed on it and transplant it into a different hardware environment. At the very least you need to do a repair install and the better option in my opinion would be to format and do a clean install.

Do you have an install disk for the operating system? Do you have a CDROM drive that you could at least temporarily attach to this PC for install purposes? The motherboard does have at least one IDE controller?

It may be possible to use a USB connected optic drive for the install but the motherboard needs to support booting to USB and it might be necessary to create your own modified install disk since I believe XP doesn't natively support that method.

"i have no disk or floppy drive from which i could stick a boot cd into, so can i boot dos from a flashdrive or what."

What is the size of the hard drive ?
If it's greater than 137gb, or if it's a SATA drive, there are additional things you need to be made aware of.

As Richard59 has said,
"....you cannot take a hard-drive with XP installed on it and transplant it into a different hardware environment. At the very least you need to do a repair install..."

.....as in, a Repair installation of Windows procedure - I recommend that if the hard drive has a lot more than just what was installed by Setup on it - for that you need to connect an internal optical (CD or combo CD/DVD drive) drive to the same computer.

In any case, you need an XP CD to fix your problem, preferably of the same version - Home or Pro (that must be the same for a Repair installation) - that's been installed on the hard drive, and a Product Key for it that's not being used by anyone else.
Even if you can set your bios Boot Order or similar settings to boot from a USB drive, the XP CD cannot recognize most of, if not all, USB optical drive models, so that's probably not going to work, and it can't recognize any USB flash drive during the initial stages of loading files from the CD - a USB flash drive has to be made bootable a well. It can't recognize most models of USB floppy drives, unless they were available when XP was first released, circa 2001, and the only thing you can do with a floppy drive is to load the 6 floppy set that loads the same initial files that the CD normally loads - you still need a Windows CD.

There is a method of installing XP from scratch when you can't use an optical drive, but you still need an XP CD, and you need to be able to connect the hard drive, one way or another, to another computer with a working operating system, and that system must have a working optical drive.

thanks, i fixed it, but i ended up just formatting the disk. rooting around i found out i had a IDE cd drive (motherboard only has 1 IDE slot, so i had to make it the slave drive on the same line as the hard drive). i then used a boot disk to format the drive then reload windows. the point is null now anyway, i upgraded to a sata 320 gb hard drive. the drive i had been having trouble with was a 70 gb IDE (sorry about not specifying that), so i think that upgrading to a better hard drive, and hopefully to windows 7 sometime soon, was simply my best option. thanks for your responses

Thanks for tying up this thread.

However, we probably could have helped you to get the installation on the original hard drive working fine if you had provided more information.
