UNMOUNTABLE_BOOT_VOLUME error! PLEA

Specs: Windows XP Home, Intel Pentium 4 / 512 DDR
Hey everyone, i'm getting really desperate here. Heres my problem

I was on my fully functional computer last night, here are the specs

-Windows XP Home
-512 DDR ram
-Geforce FX 5200
-Intel Pentium 4
-i865Gm-IL **NEW** motherboard (funtioned perfectly)

Alright, last night, the power went out while i was on the computer.

When the power comes back on, i get a blue screen saying

UNMOUNTABLE_BOOT_VOLUME

I absolutely CANNOT get past this screen, i've tried booting in safe mode, and still get nothing. I've tried TONS of commands from the recovery console. When I load up the console it asks me to choose either D:\MiniNT (Which i believe is not what i use) and D:\I386

I've tried the following commands on BOTH d:\MininNT and D:\I386

chkdsk /r
chkdsk /f
chkdsk /p
fixboot
fixmbr

I've tried them all, and i get the exact same error, i was on the phone with a good friend whos a comp technician and he had no answers, then I phoned the mobo company, still no answers. I've tried unplugging my HDD, still nothing. I am TOTALLY lost!! could someone PLEASE help me!!

Watch the POST screens at startup to verify the drives are being identified by MODEL. Do you have more than one harddrive or more than one paartition on the one harddrive? What size is the Harddrive? What service pack is included on your WinXP CD?

obviously when the power went out, the subroutines for your windows crashed with it. change your setup so that you can boot from a cd and then throw in your windows install disk. boot up from the windows disk and do a repair on the windows. if you are not able to boot by cd, have one of your friends make you an xp home boot disk.

Can't, Theres no repair option when i boot up. It gives me 3 partitions, and i can either delete, create, or set up them. I went to set up one, and it said this partition must be formatted.

You are going past the console. If you are at the format and partition screen you have passed the recovery screen.

You have to boot from the CD or from the floppies and then choose the "R" option. You will have to go into your BIOS to set either the floppy or the CDROM as the first boot device.

You don't want to reinstall...you want to fix the boot sector.

When booting up to Win XP you may get a error that reads "Unmountable Boot Volume". This is probably because your boot.ini file is messed up.

So, what do you do about it, panic and try to mount your boot in your computer...... No that is probably not a good idea.

You can boot to the XP cd and when you see the Welcome to setup press the letter R
You will get a dos prompt
Then type "chkdsk /p" without the quotes and hit enter
When that is done type "fixboot" and hit enter
"Y" and enter at the prompt
Then type "exit" and hit enter
The system will now reboot into Windows

If for some reason that don't work for you, you can boot to the recovery console like above and...
Type "chkdsk /r" then enter
When done type "exit" and hit enter.
This will take longer, but the system should boot back into Windows.

Try BOOTCFG /rebuild

Do not type anything in this space.

If there is No Repair Option when boot up, that means your Xp CD des not included SP1 or SP2. you need to Create An SP2 Slipstreamed Boot CD or Create An SP1 Slipstreamed Boot CD depend on what you have had installed (Sp1/Sp2)in your system.

I have exactly same situation. I know where that R should be -i have seen and used it elsewhere, now it just doesn´t exist on my XP installation CD´s (i have many).

So there is no any use to hit "R" because _there is no that option_.

I allready slipstreamed SP2 to XP CD.
