So I tried to get this old computer (2005) that hasn't been used in the past few years, as far as I'm aware, to work. Booting it up shows the loading screen for Windows XP before showing a blue screen with the error message: "Unmountable Boot Volume".

The technical information thing says:
*** STOP: 0x000000ED (0x8636F7B8, 0xC0000006, 0x00000000, 0x00000000)

I've seen many forums and threads that say to use the Windows XP Recovery Disk, but I do not have one. What could be causing it, and is there any way to fix this problem?

maybe if you did a full format of the drive before you reinstalled the OS (rather than a quick format) A full format of the drive will locate and mark bad clusters and sectors of the hard drive as bad so they will not be used. You might run crystaldiskinfo.exe to read the smart error data from the drive before you start to wipe the drive. (assuming you can boot) if you can not boot, then enter bios and check if the system time is correct. if it is not then your battery backup might be dead and you lost your bios configuration settings.

2 most common causes I see for unmountable volume are a failing hdd or a messed up boot file. First I would test the HDD using the manufactures diagnostics, if the drive passes you will need an xp disk(no way around this that i know of) as you need to boot to the recovery console and run a chkdsk /r.

basically code could not be loaded into memory because of a IO status error returned from your storage.


Error code: (NTSTATUS) 0xc0000006 (3221225478) - The instruction at 0x%p referenced memory at 0x%p. The required data was not placed into memory because of an I/O error status of 0x%x.

on a old machine like that, I would check to see if the date and time were correct in BIOS. if not then the battery backup might have failed and your BIOS SATA configuration might have changed. (IDE mode changed)
sata 1 came out in 2003 but many systems kept the BIOS set to IDE mode as the default. So if the BIOS settings fail you can not read the drive correctly until you restore the settings.

I would reset the BIOS to defaults and reconfigure everything in BIOS again.
very old machine can have failed electronics, the electronics will fail over time even if not in use.

guess i would also blow out the dust and check the hard drive cables.

Would it be possible to just wipe the hard drive and download a new OS on it instead?

If you buy a new OS yes, but I would still run diagnostics on the drive to make sure it's still good first.

I know it;s been a long time since I posted this thread, but the battery for the motherboard is most likely dead or something, since the time for it is incorrect (Last I checked, it said something like "September xx, 1999" or so).

ya, a dead batter will cause all o fyour CMOS data to be lost. you would have to replace the battery and make all the settings again. often the default BIOS mode for a sata drive will be incorrect after a BIOS reset and the system will not be able to boot the drive. check the BIOS setting for the IDE mode, make sure it is correct for what was running when windows was installed. AHCI would be a current default for sata, older machines used a IDE emulation mode as the default. You might even just try different modes and attempt to boot until you find the correct one.
