GPT partition changes to MBR after installing 7 Ultimate x64
Hello everyone
I tried installing 64-bit Windows 7 Ultimate on a 3TB Seagate SATA HDD. The list below shows the procedure I used:
1. Booted to the 7 Ultimate installation DVD
2. Launched Command Prompt, ran diskpart and clean and used the convert tool to successfully convert the only volume to GPT
3. Verified that the only disk in the list of disks was showing about 2.7 TB free space.
4. 64-bit Windows 7 Ultimate was successfully installed but on a 2TB partition. Looks like the partition is of MBR instead of GPT.
5. I booted to the installation DVD, launched Command Prompt, ran diskpart and clean. But this time no volume except for the DVD shows up in the list of volumes.
Please help me figure why the GPT partition which I created and verified was converted automatically to MBR after the successfully installation and how you can complete 7 on a 2.7 TB GPT partition without letting it be converted to MBR. Also, please advise me how to make the missing volume reappear in the Disk Part.
Thank you in advance,
Derek
