Hi

I don't know if this is a Dell problem per se but both my IBM machines are Dell and I'm having the same problem with both.. 

I'm trying to put W10 (Win10_1909_English_x64.iso direct from MS site) on my Vostro 200 with a startup disk made with USB Image Writer in Mint 19.1 MATE. I have used a couple of different thumb drives and a USB HDD which all test good but when trying to boot with any of them on both my Vostro 200 and 1500 laptop I get the message "no boot sector" and it reverts to GRUB. The ISO appears to unpack okay but as I don't have a working Windows installation at the moment and WINE is a mystery to me I don't know how to test the image.

I would put my money on the common denominator being the way I am formatting (tried NTFS and FAT32, checked boot flag in Gparted) or writing to my USB drives but I can't help wondering if there's another reason. Any help would be much appreciated. I may use Linux but I'm more of a nuts and bolts kinda chap so please bear with me!
