Stuck with invalid product error and legacy mode is disabled

[Pranshu8292]

The problem started with resetting my computer. In reset process system got stuck. The windows recovery failed too. Now I am getting invalid product information error, I can solve this using dmi, but while following to enter the product information through dmi I am getting this error "The uefi tool does not support this platform". I guess I am getting this error as I am booting the dos bootable usb through uefi and not legacy boot. Legacy boot is disabled currently and I am not able to change it, maybe because of the invalid product information error. I change the legacy mode to enable and after restart it getting back to disabled.

I can certainly understand the desire to do factory resets -- given the prevalent view that such an action, though extreme, will fix a variety of mysterious problems and return a troublesome PC to working condition.

Problem is -- that very often is NOT the case and if there is any hardware issue at all, which is nearly always the cause with a SLOW PC (which is why most folks do the factory resets), you end up trashing your PC and rendering it useless. So, you trade a SLOW PC for a non-working PC. Not a good trade -- and certainly not what you intended.

Since your PC came with Win10 preloaded in UEFI mode, you need to create install media to support that.  If you have the Win10 ISO file, you can do that using the free RUFUS utility -- which you can get from here:  https://rufus.ie/en_US/

When you then reboot using the new media, it should install without issue.
