I've had a lot of problems lately and now I'm having problems logging in at the login screen. I'm giving up and just want to reset and start over. How can I "factory reset" Ubuntu, in this situation, or, for future reference, in general?

I want to reset Ubuntu. I have searched it on Google many times and I am new to Ubuntu so I am wondering how to reset it without too much complication. I have already tried re-installing it but my computer will not boot from the DVD. I am using Ubuntu 14.04.2 LTS.

I want to completely delete everything and have it start like it did when it was originally installed. Completely erase everything and restart, reinstall, and reconfigure Ubuntu.

I have an ASUS EEE PC 1011PX with Ubuntu Linux Desktop Edition v 10.10. I want to revert its state before its first start where a wizard came up and asked things username, passwords, etc... I hope there is a command or something to revert everything back to the first start.

I had a problem with a disk and ran badblocks.

So now when I run dumpe2fs (also from e2fsprogs):

sudo dumpe2fs -b /dev/sdc1

I get a list of bad badblocks such as:

dumpe2fs 1.41.11 (14-Mar-2010)
192
1592
2416
3112
3552
...

But in fact, I realised that the problem came from the rack and not from the disk. I was using the rack in eSata and got plenty of read errors. Now i switched to USB, it's not as fast, but no errors at all.

So my question is:

How do I reset the badblocks list stored in the inode #1 (badblock inode)? (of course, without reformating!... That's the last thing I'll try if I get no solution)

Because apparently blocks are not at all "bad", they were just reported so because the rack is faulty.

Edit: I tried to run another badblocks once the disk was connected to USB but no success: previously found bad-blocks remained. I ran:

sudo badblocks -i /tmp/emptyList -s /dev/sdc1

the file /tmp/emptyList being empty so that badblocks is fed an empty list of known bad blocks. But apparently, it's not THE list of bad blocks, it is the ADDITIONAL list of bad blocks, which would be added to the existing ones declared in the inode #1. The documentation (man) is not very accurate about that.
