What is likely happening is that the field that was not correctly updated was early in the disk (e.g., in the boot-record or partition table) so when the VM BIOS tries to read the disk, it is finding incorrect/inconsistent values and throwing an exception.
WINDOWS XP BOOT DISK READ ERROR OCCURRED UPDATE
What likely happened was that when you resized the VHD file, the tool that you used had a bug and did not (correctly?) update a field somewhere in the file-systems of the disk (partition table? boot-record? boot-sector? NTFS meta-files?)Īs others have pointed out, the error you are getting is usually a BIOS error as opposed to an OS error. The fact is that there are a lot little things that can go wrong, or worse, that can “go not wrong” yet still be incorrect (i.e., an incorrect value could show no symptoms). Even an old copy of Norton Disk Editor doesn’t complain about that disk.
WINDOWS XP BOOT DISK READ ERROR OCCURRED WINDOWS
For example, an old copy of Partition Magic complains about some little numeric inconsistency or something about the partitions on one of my disks while Windows (XP) and Easeus Partition Master and such all chug along without issue. You will now be greeted with the first error - indicating that the Windows XP loader doesn't like the disk.įile-systems are intricate, complex, finicky things. Now do the same thing as the last step, but use /NT52 instead of /NT60.

(Although it won't find Hal.dll, at least you know it's working.) (The location of the tool is likely to be C:\boot\bootsect.exe, but if it's not there on your system, then you'll need to find it somewhere else.) Now un-mount it, and try booting. Now try mounting the VHD in Windows's Disk Management, and running BootSect.exe /NT60 X: /MBR, where X: is the drive letter of the mounted volume. (While the error is different, it's the same issue.) Notice that you'll be told "Error loading operating system".
WINDOWS XP BOOT DISK READ ERROR OCCURRED DOWNLOAD
I made a sample VHD file illustrating (almost) the same problem which you can download here.ĭownload the file (it's highly compressed, be careful!), and try booting it in VirtualBox (or some other VM). I just want to know what's causing this problem, in case I run into it again on a physical machine (which I have done before). I have nothing to lose, so I don't care about fixing it. So "re-format the disk", "reinstall Windows", etc. I'm interested in knowing the cause rather than the fix. My host OS reads the VHD and the partition completely fine The partition starts at sector 63 (it also did so before the problem) of cylinder 1, head 1, and is marked as type 0x07 (NTFS) When I resized the VHD file (and the embedded partition), and tried booting, I got: A disk read error occurred I have a virtual machine containing Windows XP SP3.
