hard disk Problems.

Hi, i have a customers computer Gateway SX2110 it used to have windows 8 and my customer wanted to get windows 7, so i proceeded as usuall but started to have problems with the boot.So I took the hdd, put it in another PC and installed windows 7 on that. I deleted all three partitions that the hdd had on it, OEM, System Resever, and Power Reset Button (something like that, it was the Recovery partition) because it would not let me install windows 7 on any of the partitions since they were all linked together.

So installed Windows 7 on it, and popped it back on the other PC.

Lo and behold, It would not boot. I keep getting the error message " Error: No Boot Disk Has Been Detected Or The Disk Has Failed".

I checked the cables, they were working fine. I switched sata ports, no avail. I plugged the HDD back on to the other pc and it was working fine again.

I decided it was probably Windows 7 incompatible, so I took a win 8 image and installed it back on to the HDD using the working pc then popped the hd back into the Gateway. But it still gave me the error message.

I also tried completely formatting the drive and installing it blank see if it would at least say something else, but same error message.

At this point Im thinking that installing win 7 might have deleted something that the BIOS needed in order to boot properly. Everything is in perfect working condition hardware wise (except maybe the WAN mini port which started all of this.)

Any help and suggestions would be much appreciated.


* Note that i havent been able to boot either USB, CD, DVD, External DVD unit, USB or Ethernet. on the gateway pc.


**If this post isnt on the rigth place i apologice and could please be moved to the correct place beacuse i couldnt find a "Hardware PC problem" section.

 

but i just installed w7 on it , with another pc. it seems to work just fine.

i even made some copy-paste data. it worked 100%.

 

i placed the HDD of the gateway on my PC case, and installed windows 7 on it ,and i transfered music from a USB to it, and backwards.

didnt had any problem.

 

when i try to format the Gateway : cd & dvdv -> Hard Disk -> Lan -> Removable Device.

and when i did the format on the other pc and placed back the HDD : Hard Disk -> cd & dvd -> Lan -> Removable device.

 

i did that and it didnt worked.

But i just changed something at the bios and worked.

i went to the advance booting options and theres an option of CSM boot wich was disabled. but wasnt able to change it beacuse of the secure boot, so i had to disable the secure boot so it could let me activate the CSM boot, and Voilaa, it worked.

As im typing this im installing w7 on the gateway.

Thx a lot Valis for your support and assistance.
