Win10 won't boot on newer computers

[Trozza]

Thanks, I've tried re-organising the partitions. However, I don't know what happened but I can't seem to be able to select a boot partition. I wasn't sure what was meant by "The destination boot partition must be 20% larger than the used space on source boot partition." but I figure it could relate to my problem. I tried creating different sized boot partitions but didn't have any luck in being able to select a partition. I also attempted a single fat32 formatted partition, but didn't get anywhere either.

The boot partition must be a primary partition, it cannot be a logical partition.

Thanks, that was the issue! I only had the primary partition as the system partition.

Also I have installed Windows on the hard drive which has had it's partitions reorganised so that it goes System -> boot -> other partitions. It now all works. YAY! It's strange that the newer computers couldn't handle the partition order, when the older ones could.

thanks again, I'm a happy camper now!
