R61 with Vista Business freezes

[Raiko]

Got a new R61 which worked fine until I did the following:
1. Shrunk the NTFS partition - still working fine after this
2. Created space for IBM boot manager
3. Created new partition and tried to install OS/2 - Trap on 2nd boot
4. Vista would not boot
5. Formatted C drive and reinstalled Vista from back up CD's
6. Vista now boots OK
Problem: Now Vista freezes/hangs after 2 to 10 minutes of using it.
Cannot find any errors reported anywhere, PC-doctor runs all tests
and does not report any problem.
Any ideas anyone?

Discovered that the c-drive had increased to nearly occupy the whole disk after installing from back up CD's. I've shrunk it to approx a half and Vista has now been running stable for an hour......

Does anyone have a good procedure for reating a multi boot with eCS/OS2 ?
