Hello All

I have a very big problem,

I am installing call manager 6.1 on a CISCO MCS 7800 Series Server MCS-7825H-3.0 server. On reboot I get teh following error

GRUB Loading Stage 1.5

Grub error 21.

Any ideas ?

Thanks

i got this error during our upgrade bc cucm 6 wouldnt support RAID on our platform. we had to remove one hard drive and start over.

Thank you for your reply

I changed the RAID configuration to the default and it works.
