System won't boot after defragging: should I run Fixboot or Fixmbr

All I get is a blinking cursor. Here's what happened:

Just finished a fresh single-partition NTFS-format and Windows 2000 SP4
install on a Maxtor 80gb IDE drive, fully Windows-Updated it, and loaded up a
suite of programs. During the numerous reboots required, it always booted
fine and everything was running smoothly.

From the C: drive Properties/Tools menu in Explorer, ran Error checking
(with no switches); it reported no problems. Then ran Defragment in analyze
mode. It reported bad fragmentation, so I booted into Safe Mode (for access
to as much of the disk as possible), deleted as many temp files as I could
find (Temp Internet files, \Docs & Settings\Administrator\Local
settings\Temp, \WINNT\Temp), and ran Defragment.

It defragged fine, very clean-looking result, then ran Error checking again
with no switches, it reported no problems. Next step was to create a
Emergency Repair Disk, but unfortunately I rebooted first.

Now the disk won't boot: I get a blinking cursor in the upper-left corner,
which quickly drops down to a second line, and remains blinking; no progress
from there.

My inclination is to run the Recovery Console from the boot disks, and my
question is which command should I run from there: Fixboot or FixMBR?

I don't want to make unnecessary changes to either one. MS-KB and elsewhere
seem to indicate that FixMBR is more for virus damage to the MBR.

I can run the drive as a slave from another disk (with the same OS install):
Error checking still reports no problems, Defrag analyze mode reports the
same clean result, all files (including the C:\root) look intact and read
fine from Explorer, and an Avira virus scan detects nothing.
 
"reported bad fragmentation"

This doesn't sound right. How big is the boot partition?

By 'bad' I mean there was a lot of red in the initial Defrag Analysis
display. It was all cleaned up and changed to blue after completing defrag.

The disk was formatted while running as a slave drive from Explorer in
another installation of Windows 2000 SP4. Since the Explorer format menu
provides no partition option, it's presumably a single partition of the full
80 gb (ie, 74.5 gb). That's the drive's capacity as reported by Explorer
Properties. Used the default Format menu settings: NTFS, 4096-byte
allocation, no quick format.

The C:\ root system files appear intact. I'm unsure whether to run Fixboot,
FixMBR, or both.

You can use the Disk Management snap-in to manage disks in Windows

Start|Run|diskmgmt.msc

Better to let Windows setup create and format the partition for you. If this
80 gB partition or the system partition is part of a disk larger than ~136
gB in size then you now know the problem.

Also be aware that Microsoft use the term boot partition for the partition
where the operating system is installed, while the system partition is the
first primary active partition (where the boot sector and files required to
start the operating system reside) The system and boot partition can be
one-and-the-same.

Thanks for that partition info. Any advice on how to get this disk
booting again? AS noted, all files appear intact.
 
Not really. Not without some details. Where is system partition and disk
capacity?

Disk capacity is as reported at the top of my post: physically it's an

Where is the system partition? What size is the disk it resides on?

As noted, I used Explorer's Format menu to format this disk, thus
don't know where the system partition is. How can I find this
information?

The size of the disk on which the partition resides is 80 gb.
 
Disk Management has this information. You mentioned the boot partition drive
letter is "G" so I suspect the system partition is on another disk. If this
disk size is greater than ~137 gB then you have problems.

I fed you all the info I could find in Disk Mgmt, didn't know what
else you were looking for.

It's listed as drive G: because I'm accessing the 80gb disk while
running another install of W2k from a separate hard disk (since the
80gb won't boot).

No, this non-booting is a different disk from what we discussed in my
other post about crashing/the 137gb limit.

Since last posting here, I ran a HD Tune utility test on the 80gb
drive, it reports a bad (ie, 'failed') seek error rate. That may well
explain the bad fragmentation reported after the software installs.
Looks like this disk is failing and I chose poorly.

I was trying to avoid the 137gb issue by going to this smaller disk
for my OS. But based on the advice received in my other post, I feel
confident now using the 200 gb drive for the OS with the EnableBigLBA
fix running.
 
The system partition is the first primary active partition (where the boot
sector and files required to start the operating system reside) Generally
where boot.ini, ntdetect,com and ntldr reside.
