Windows 7: Windows could not update the computer's boot configuration

[mangotango99]

I have a Samsung laptop a few years old - Core i7, 2TB HDD, 8gb Memory. It was supplied with Windows 7 and I have the W7 installation dvd that came with it.

Over the years I have booted from this DVD and re-installed a fresh copy of W7 several times with no problems whatsoever.

A few months ago I succumbed and upgraded to Windows 10 - no problems - it all ran fine.

I wanted to go back to W7 so I deleted all partitions on the HDD, booted from the W7 DVD as usual. Selected country:UK and created a new partition on the HDD (whole of the HDD). Files were copied to the HDD in the usual manner, Windows 7 installed up to 100%, then onto features etc. The installation went with no problems up to the fourth step - installing updates. I though it was a few seconds away from completion and re-boot. However, I then got the message 'Windows could not update the computer's boot configuration'.

Repeated several times, deleting and re-creating partition on the disk but the same happened.

In the end, I installed Windows 10 on the HDD by booting from a USB stick with W10 on and it installed no problems.

Anyone got any idea what it going on? It looks like my install of W10 has changed the disk somehow so W7 cannot ever be installed again on the disk.

Hi and welcome to SevenForums,
Clean installing windows has been rather interesting no doubt,
Win-10 did have a round of updates that did have a lot of issues for some people
Many reported bios and boot files changes

For win-7 that is a issue seeing win-7 doesn't support secure boot features
So in your bios see if secure boot is activated and see if OS Type is set on windows uefi mode if it is set it to Other OS instead

As far as updating win-7 on a clean install
