Today I try with 2 pcs 1 Toshiba and 1 Dell... all I5 Quadcore + 4Gb ram.
All do not boot with SSRD 2011 with last Live Update and personalized CD.
I will try with Multilanguage from fileconnect ISO 10.0.1.41704 SSRD
I have done a disk cleanup, but I have the same problem.
Additionally I try to uninstall SSR 2011 and now I have a new problem !!!!
See the attach, please.
If I confirm OK the uninstall script loop and popup the same error !!!
I have had the same problem on Toshiba and Dell.
In BIOS I disable multicore features before boot SRD.
After I restore the BIOS feature
I hope this trick will be good for you.
