A friend has a laptop
with brand new Core i7, 16 GB RAM, 1 TB SSD and 2 TB HDD.
He told me that he installed Windows 10, which was running fine, but discovered that it was 32-bit & "tried a few things" to install 64-bit. None of these "things" involved opening up the laptop, but that's about as much sense as I can get out of him.
I have his permission to delete everything, just get Windows 10 64-bit installed.
When booting UEFI, the laptop doesn't recognize an USB stick or USB DVD (he replaced the internal optical drive with the HDD). So, I am booting in legacy mode.
I can do anything – except open the laptop. My resources are Linux on USB drive and Windows 10 64-bit ISO, which I have also put onto a USB drive.
I made sure that both drives are MBR, rather than GPT (not that it matters, as he has max 2TB).
When trying to install, it blue screens with seemingly differing error messages each time, one being an exception in ntfs.sys, and one saying:
Windows cannot install required files.
Rather than chase after the errors, can someone tell me how to install, given that I can format/delete anything.

That worked for me to (ymmv)
