1421725 2016-06-11 04:42:00 Hi,

I recently upgraded my PC to new SSD 240G drive, installed a fresh Win7 install on it. Everything was going fine for a few days until I added new 1 TB seagate HDD to the system as storage. Since then every time my PC boots up I get a error message saying no boot record found. I have to physically disconnect HDD, boot into windows on SSD then reconnect it again. After days of searching the net I found it has something to do with SSD being GPT drive, and HDD is a MBR disk.
My question is: is there any way to convert SSD to MBR without the hole shebang of reinstalling windows, drivers, updates, programs etc. ; or some tinkering with BIOS perhaps ?
Any advice hugely appreciated.

By the way booting order in BIOS is set to: 1. Windows Boot Manager, 2.SSD, 3.CD
once I change it to 1. SSD, it will not boot.

Thanks very much
Mark

1421726 2016-06-11 05:36:00 Boot manager sounds right. Is it 64 bit? If it is disable secureboot (if it's enabled), Win7 x64 doesnt support it Speedy Gonzales (78)
1421727 2016-06-11 06:42:00 hi, it is 64 bit, where do I find secureboot? its not listed in Gigabyte Bios settings.. miras2000 (10652)
1421728 2016-06-11 07:43:00 The boot manger must be used other wise it wont boot ( as discovered) Just make sure when attaching the 1TB drive the boot order hasn't changed ( it often will) to answer the other question.

Heres the full instructions: technet.microsoft.com BUT as it points out
If the disk has a volume on it, you can’t convert it back to a basic disk. You must delete the volume before attempting to convert the disk back to a basic disk. Guess what that means :(

1421729 2016-06-11 07:53:00 Is there a possibility of creating image/copy of existing win7 installation and then, after conversion to MBR, restore it ? miras2000 (10652)
1421730 2016-06-11 07:58:00 hi, it is 64 bit, where do I find secureboot? its not listed in Gigabyte Bios settings..

I think it's normally in the BIOS. Dont know where it is on yours tho, I've never built a GB system
