your information is extremely rare.
Could you please:
- exactly state what hardware you are using?
- at which point exactly the problem appears?
- did you receive any kind of error message?
- what's going on after the reboot?
- Did you take out the CD from CD-drive during reboot?
- or are you running again into the setup procedure?
You should read thisthis
to learn how to ask a smart question. As stated the information you provided is so spare, no one can figure out what exactly your problem will be.
Also did you check some of the available SuSE forums? If you use SLES eventually you have support by SuSE/Novell which can help you.
