Usually disk enumeration starts at sda. So I presume you have a very unusual configuration of disks and USB sticks. Could you describe it?
Could you provide whole partition table ? I see no partition on your sde disk.

When I loaded Ubuntu 10.10 I did a complete new install. I formated the whole hard drive and just let Ubuntu take up the whole thing. I did not do a dual boot only ubuntu. That is why I assumed that sda1 would be for the boot record. I have been using Linux since the days of caldera. then went to Mandrake and mandriva and finally ubuntu for the last 5 years or so. This is the only time I have ever lost the boot loader. I am not much of a tech guy that is why I like ubuntu. but even loading gparted, I can't find any partitions however it only shows 465.76 gb of my 500 gig hd. So I can only assume that the other 34.24 gig of the hard drive is where the boot, swap and ubuntu live. It shows no other partition and shows the 465.76 gig as unallocated. The only thing I can attribute it to is that I downloaded the last two updates on two different occasions and the first of those I did not restart like it recommended and then I waited until I had downloaded the
 next update and then did a restart. At that time all I got was a black screen when it restarted. It works fine with the live disc. so I don't think there is anything wrong with the computer.

I never was able to find the partition where ubuntu resided. I gave up and did a fresh install. However this time I set up a seperate home partition. Maybe that will save my info in the future. Thanks for your effort anyway.

Avoid posting with previous message included. It made thread unreadable. Remember each time I read the whole thread to remember the question.
About GBytes of disk, it's hard to measure as you have both GBytes and GiBytes, and also 10% reserved for OS.
Don't restarting immediately after an update is not as issue. What can be an issue is installing a new kernel, as sometimes Grub2 configuration is badly rebuilt.

"Maybe that will save my info in the future. " Yes!

Sorry but if you receive an email from me that the subject liine is: Important - Very Important - With Best Regaards - Its amazing - Hello - Very Amazing or something similar please just send it to the trash or the spam folder. I dont know how but I was hacked.  I use Linux so it didn't bother my computer other than send it to everyone on my email list. So please don't open it. Sorry for the inconvenience.
