I did the download with Mandriva and the burning by k3b-ISO with the lowest speed (2x) by using the first computer.
My first computer are ASRock M3A770DE, AM3 dual-core, 8 GB RAM, Radeon HD 5450,
the second MSI K9N6PGM2, AM2 dual-core, 4 GB RAM, Gainward 8400GS.

When I put in the DVD my first boot-device are CD-Player in BIOS (DVD) but it start from HD. After 4 or 5 times starting the computer it begins to start from DVD, but very slow (need till 10 min starting) and than are following all the error-messages.

At least I try the i386- and amd64-version of kubuntu 11.10.

I did download kubuntu 11.10 and try to install but it do not work. First I set "start from DVD" but the computer do start from harddisk. Than after it show me
"chroot: can`t execute dpkg-divert : input/output error"
After download and burning DVD I compare the burning files and the program tells me that all will be ok.
What will be the problem?
Old Windows Settings from years ago?
