Unable to install Ubuntu 7.10

Try this:
username: ubuntu (in low case)
And a blank password.

If it doesn't help then your cd or download may be defective. Try to slow down the burn speed (4x). Or try another CD-Drive.

Hello gupta...

Firstly,I suggest you check out the download site http://www.ubuntu.com/getubuntu/download

Next,Choose a location near you and download the ISO. Then follow the directions at https://help.ubuntu.com/community/BurningIsoHowto (Burn your cd at a lower speed say at 4x and check your MD5 sums)

Bit info about MD5 sums:
With an md5 sum you can compare the contents of files. If your .iso file is defect (this can happen when you download it), it's md5sum would be different than that one on the Ubuntu server.

To calculate the md5sum of your image file, you can use a command line tool like http://www.md5summer.org/download.html for Windows (on Ubuntu it's the 'md5sum' command). Then compare the calculated value with the ones in this list http://releases.ubuntu.com/7.10/MD5SUMS.
So if you have the ubuntu-7.10-desktop-i386.iso, the calculated value should be d2334dbba7313e9abc8c7c072d2af09c.

If the file has a different md5sum than expected, I would recommend to download that iso again.

Next,Make sure that all equipment is turned on. Do a clean install, delete all the partitions and this time create a separate /home and any others that you think you may need.

You can also see screenshots of partitioning here:

Hope it helps
