Hi all, I was trying to clean install Windows 7 on my client's computer, but it always ends with the error code 0x800700B7: "Windows Cannot Install Required Files" in all mode (either booting it from DVD or running the clean install routine through the existing windows installation itself)... I tried to swap the medias, from UFD to the DVD, swap dvds, from the murphy78's AIO dvd to original MSFT media, but it still end up the same.. I even tried to upgrade it to Windows 10, but it still ended up the same... Was the partition table messed up or something else had happened? I checked everything and the only thing that is wrong from the PC is the main OS drive has no free space and I had solved it... my instinct says that the partition table was messed up....
Boot from the W7 DVD and start a new installation. Delete all partitions and create a new one. Format the partition as "NTFS quick" That will give you a clean install and an uncorrupted partition table. (This will destroy all data on the drive. Copy any files you want to save - pictures, documents, etc. - to another drive before you do this)
test ram and disk properly. hirens or some winPE tools. c: 100 MB is the hidden boot partition (shouldnt say C.. the other is the big one with windows and all files.. thats C: try this. unplug SD card readers and any other hdd except that one for win7
But this is unlikely.. I've tested the image on a real metal and a vm.. and it works.. :/ as for the corrupt burn, how can a MSFT made DVD get corrupted?
what if I just go ahead and use dism from another pc to upload the windows 7? would it tturn into another bigger disaster? so, I'll just mimicking what setup.exe does in command prompt from another pc..
