You sure it's not Win2000? :-)

Anyway, I see that you have Grub2, Syslinux, Grub Legacy installed.
============================= Boot Info Summary:
===============================

 => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at
sector 1 of the same hard drive for core.img. core.img is at this
location and looks for (,msdos1)/boot/grub on this drive.
 => Syslinux MBR (3.61-4.03) is installed in the MBR of /dev/sdb.
 => Grub Legacy is installed in the MBR of /dev/sdc and looks at sector
70721 on boot drive #2 for the stage2 file, but no stage2 files can be
found at this location..

Looking at your sda1 /etc/fstab (starting at line 608) it shows:

Boot on:
# / was on /dev/sda1 during installation
UUID=8082b8f5-a462-45a4-aedc-25e2f8a903c3

Home on:
# /home was on /dev/sda5 during installation
UUID=f77b063d-db03-4169-8330-5040d4df2581

/usr on:
# /usr was on /dev/sda6 during installation
UUID=22615e5a-1464-4812-87bd-c59d5505b53f

/usr/local on:
# /usr/local was on /dev/sda7 during installation
UUID=86f09b0e-bd94-45bc-b202-d6a958e377c2

Swap on:
# swap was on /dev/sda9 during installation
UUID=59144d19-ad02-4079-a02e-328ce9e7f2b9

Now looking at the blkid's (starting at line 206):
"blkid" output:

And those look OK... until we get to sdb1:
/dev/sdb1        453E-ED44  vfat       Xubuntu11
That is a vfat file system (syslinux), but you are showing "Xubuntu11"?
is this where you installed Xubuntu? If so, the boot section would need
to be unencrypted in order to boot.

Mount points are showing sdb1 mount point /cdrom.
/dev/loop0       /rofs                    squashfs   (ro,noatime)
/dev/sda1        /media/8082b8f5-a462-45a4-aedc-25e2f8a903c3 ext4
(rw,nosuid,nodev,uhelper=udisks)
/dev/sdb1        /cdrom                   vfat

Now go looking for sdb1:
line 656 sdb1/boot/grub/grub.cfg
"menuentry "Try Xubuntu without installing" {
	set gfxpayload=keep
	linux	/casper/vmlinuz  file=/cdrom/preseed/xubuntu.seed boot=casper
quiet splash --
	initrd	/casper/initrd.lz"

etc. etc. Are you trying to boot from sdb1? Does your grub boot message
show which device it can't find?

I'd recommend reinstalling Grub2 to sda via the liveCD:
https://help.ubuntu.com/community/Grub2
 https://help.ubuntu.com/community/Grub2/Installing
  https://help.ubuntu.com/community/Grub2/Installing#Reinstalling_GRUB_2
[Reinstall from the LiveCD]
...
sudo mount /dev/sda1 /mnt
sudo grub-install --boot-directory=/mnt/boot /dev/sda
sudo grub-install --recheck /dev/sda
sudo update-grub
sudo reboot

Feel free to contact me off-list directly if you run into problems.
