I ran into a problem with Ubuntu 13.04.
I installed it without any problems. When I reboot my machine it hangs on a black screen with a blinking cursor after grub.
- I tried recovery mode as well and it hangs at
switching to clock source tsc
. - I tried the nomodeset parameter for the kernel, but it results in the same.
I used a dualboot Ubuntu 12.04 & Windows 7 before, now I only want Ubuntu 13.04 alone.
Can someone help me with that?

Try booting from Ubuntu install CD:
if it doesn't work, try chrooting:
Debugging grub loading:
Hold shift during boot, then hit e to edit the GRUB entry. Remove the part that says "quiet splash" and replace it with "text" to see what's happening during boot.
Have a look here: Linux kernel hangs at 'Switching to clocksource tsc" on Pentium 4.
and try to edit the boot entry (just add
clocksource
either withhpet
oracpi_pm
value):If it works you might want to change in
/etc/default/grub
this line:then run
