Win 7 32bit installation problem on GPT disk
I would request any body to help me on following issue.
I was runing Win 7 pro 32 bit on lenovo B470 laptop with i3 processor, 2GB RAM, 750 GB HDD. I thought to upgrade 32 bit to 64 bit as I got Win DVD from market.
In first attempt upgrade was un successful but after lot of search on net, I finally found that Win 7 64 bit does not install on Mdr partition. so I saved the data and unallocated all the partitions and did a clean installtion. After installation and update I found two problems. 1. Laptop was not shutting down. Even not going to sleep or hybernate. I used to manually press the power button to shut down the laptop. 2. During power-on F2, F11 and F8 keys were not responding. This means that I can not see BIOS or change the boot sequance.
I found lot of information on net regarding both the issues but unfortunately the information is either not correct or not complete. I have installed all the drivers correctly but problem is still there. I intend to shift back to 32 bit system but problem is this that I can not convert back to Mdr disk as I can not access command prompt at boot and change boot sequence( due to f2, f11 f8 key not responding). Even while deleting partition from comd prompt from start menu or disk management, it says I can not delete boot partion and it can be only deleted on start up. any one can please help me what wrong I am doing?
