MBR partition table? Windows 7 won't install on hard drive that previously had win7.

We don't know why the original Windows installation you had stopped working, it could be that the disk is failing...or it could be anything else.  You should go to the disk manufacturer's web site and get a diagnostic utility that will tell you if the disk is bad.  Most of these utilities also have options to zero fill fill the beginning of the disk, maybe the newer ones also have options to fill the end of the disk, that would take care of the GPT/MBR confusion, the disk would then be seen as a new never used disk.  If the disk diagnostic utility doesn't have a selective zero fill/wipe option then you can get a disk editor like Active@ Disk Editor that will selectively allow you to zero fill sectors at the beginning and end of the disk, filling the first and last 100 sectors will put a definitive end to the MBR/GPT debacle, the disk will be seen as new one.  If the manufacturer's disk diagnostic utility reports the disk as good and if the beginning and ending sectors are wiped then the problem is not the disk itself.

Ok, so I finally got rid of one of the errors, it seems setting the SATA mode to compatible in combination with the MBR setting on diskpart seems to remove the error telling me that my computer may not be able to boot from the disk. But everytime i try to format the partitions or continue with the install, i get the same error.. the code is 0x80070057 I think i might have a bad disk... I dont know.. I found Microsoft's page where I can download the iso file i need, so im going to make my own boot disk later... cant do it currently because for whatever reason, english isnt an option for the download... which i think might be linux... then again maybe not.

ok i tried the things you mentioned except for making boot media i dont think i cam do that now, i have no access to dvds right now and i have a 4gb isb stick on me so ill try that at home, but im going to try the install again and take pictures of the process...

okie dokie, will do...

Going back to your first post, you said Windows stopped responding.  When you then reformat and try to reinstall the installer errors that you're trying UEFI install to an MBR disk.  But you saw no boot choice for a UEFI DVD  that you remember? 

I'm thinking its possible the original OS failure was some kind of firmware change or failure from BIOS<>UEFI that would cause Windows to become unbootable.  But we can't know now which format because you reformatted to MBR before that first attempt.  In addition there are no detectable settings for UEFI.   Do you by chance have a backup image of the old install, or did you ever see in Disk Mgmt if it had a System Reserved vs. an EFI System partition? 

Looks like you have the latest BIOS version 43 from 2011. 

Did you F9 to choose Setup Defaults, then F10 to Save and Exit?  Try install then. 

Next set SATA to AHCI, F10 to Save and Exit,  and try that.

Next set DVD drive first to boot in BIOS using the navigation keys shown to change the order, then F10 to Save and Exit.  Try install again.

If these fail try to obtain a new WIndows 7 ISO image file if possible, or if not  extract the ISO image file using  ImgBurn 2.5.7.0 - FileHippo.com - making sure to avoid any sneakware during install of ImgBurn.  Then write the ISO to 4gb+ flash stick using Rufus  with the settings exactly as pictured here:


Then boot the stick using the BIOS Boot Menu Key

to see if it shows up as a UEFI device to boot and/or will install. 

If not write the same ISO to stick using Windows 7 USB-DVD Download Tool  or

UltraISO Software To Create Bootable USB Flash Driveto try it for Legacy install. 

Then the next thing I would try is to burn DVD or create  flash stick that will install either version with Media Creation Tool for WIndows 10 to compare if it will install.  This will rule out the Windows 7 ISO or media creation process is the problem and inform us better about UEFI vs Legacy install behavior on that PC. 

If no UEFI choice shows up at any time in the Boot menu then I'd abandon that effort altogether and focus on new ISO, new media, disk wiped and converted to MBR again to compare WIndows 7 and 10 legacy installs.  You do not need to install 7 first to Upgrade to 10, you can if desired Clean Install Windows 10 Upgrade
