i have ssd main hd. installed windows 7 on it. had created partitions reserved unallocated 15gb ubuntu. windows works without problem. took iso of whold ssd backup. brend new pc new windows 7 64 bit cd.

when try install ubuntu 12.04, not see partitions @ on /dev/sda. sees unallocated space. did several internet search got fed looking answer , tired.

tried installing ubuntu first when try install windows 7 after, says sees disk being gpt partition. went restore /dev/sda windows on , trying install ubuntu 12.04


sudo fdisk -l

warning: gpt (guid partition table) detected on '/dev/sda'! util fdisk doesn't support gpt. use gnu parted.

i think easiest thing may start over, reinstalling windows onto mbr-partitioned disk. require reinitialization of disk mbr. it's ssd. gpt-partitioned disks designed on 2tb size limitation inherent in mbr-partitioned disks. don't believe ssd size on 2tb.
