Ubuntu

windows install problems

Asked by William Coats

I have been trying to install ubuntu/kubuntu 8.04, since it came out, in a windows install option and I keep getting the same error message after it has installed all of the files. Could not access the CD, please make sure other applications are not using it and try again. There are no other programs running that are using the cd player. I even tried booting windows into safe mode with networking and logging in as administrator and keep getting the same message. When I check the c: drive the ubuntu folder is there and seems to have files in it but not all of them. When I reboot I never get the screen asking from which OS to boot into. The only options the error message gives are retry and cancel, retry just goes back to installing the files again and then I get the error message again. I am running a win xp system with a 2.2 gig amd 64 x2, 2 gig of mem, a nvidia 8600 with 256 meg of mem, 3 sata hard drive a 2 dvd/cd writer.

Did you burn the CD in such a way that the steps specified here:-
https://wiki.ubuntu.com/BurningIsoHowto
are relative to those you used?

Also did you compare the MD5SUM of the ISO file you downloaded with the correct MD5SUM as given here:-
https://help.ubuntu.com/community/UbuntuHashes

I just re-downloaded the iso, ubuntu-8.04-desktop-amd64.iso, and checked the md5sum against the ubuntuhashes page and the download is correct. I then burned it onto cd using NERO and had NERO check at the end to make sure the image was burned correctly. Nero says it is burned correctly. I checked wubi.exe from the burned disk against ubuntuhashes and the sums are different. the hash page says the value should be cdd32124f23b455b0aa22cc3ff35ff35 and I get a value of a96aa69961f3ed80dd7a88fae1e28196. When wubi runs trying to install it runs the checksum check at the beginning and everything seems to pass, but I still end up with the same error message.

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/8.04/MD5SUMS.
So if you have the wubi installer, the calculated value should be cdd32124f23b455b0aa22cc3ff35ff35
Or if you have amd 64 version of 8.04 (only and without wubi-install) the calculated value should be 8895167a794c5d8dedcc312fc62f1f1f

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

Hope it helps
