Boot from SAN error

[Hythim Ali El Hadad]

Hi,

I'm installing windows 2012 r2 for Hyper V on UCs booting from SAN [DELL]

I faced many error during installation and can successfully finished two servers but the other servers still couldn't be solved

Please check the attached error and advise what may be the problem

I used these steps to solve the partition creation error for one server

Start DISKPART

Type LIST DISK and identify your HDD disk number (from 0 to n disks).

Type SELECT DISK <n> where <n> is your HDD disk number.

Type LIST PARTITION

Type SELECT PARTITION <n> where <n> is your partition number of the last drive (Drive 0 Unallocated Space 20 Gb) Type CREATE PARTITION PRIMARY

Type ACTIVE

Type FORMAT FS=NTFS QUICK

Type ASSIGN

and will try this one for read only disk error

DISKPART> attributes disk clear readonly

Please advise for these errors

Thakns

Thanks Walter for your response

but do you know what may be the reason of this error specifically :

" The selected disk isn't the computer boot disk "

Thanks
