Actually it's fdisk /mbr - with a
That doesn't run Fdisk the normal way - it's an undocumented way of re-writing the Master Boot Record on the hard drive, a tiny bit of data at the beginning (outside edge) of the hard disk that the user cannot normally see.
XP doesn't have Fdisk, but it does have fixmbr in the Recovery Console, which does the same thing as Fdisk /mbr.
Fdisk can be used for a FAT32 or previous FAT partitions, but not for NTFS partitions .
"as well as a bad functioning MBR"
There CAN be a bad sector in the MBR, but the user and the operating cannot normally see it, and if there were, the hard drive probably wouldn't boot!! You had a bad sector the operating system DID see, so that has nothing to do with any bad sector there might be in the MBR!
You don't normally have problems with the MBR! It can't possibly have anything to do with your restore point disappearing!!
You can use Fdisk to re-partition a FAT or FAT32 partition, it does check for bad sectors and mark their location when it finds them so they are not used, but doing so wipes the previous partition tables that tells the operating system where the files are. You DO NOT use Fdisk if you want to be able to access the data that was on a partition!
Your restore point is probably gone forever.
"Hard drive with bad blocks denote the hard drive is slowly dying."
All modern hard drives have a small perecentage of their space reserved so that the automatic error checking routines the drive performs can swap the locations of bad sectors with good ones as they are found without the user being aware of that. Because of that, your hard drive normally has no bad sectors "visible" to the operating system or the user, and appears to be error free.
When a drive is failing, eventually all the reserved sectors are used up and any further bad sectors cannot be hidden from the operating system or the user.
Therfore, if you or your operating system encounter ANY "visible" bad sectors, the drive is already failing!
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
If the hard drive itself DOES NOT test okay, you need to copy or backup the data you can't install again that you don't want to lose to somewhere, and get yourself another hard drive!!!
If you haven't done so already, make the Recovery CD set for your system using the Acer program in All Programs somewhere to do that while you still can!
You will need the Recovery CD set to load the blank hard drive!
It cannot be loaded from a single Recovery CD! The single CD requires the data contents of the second partition on the original hard drive!
