I have an old laptop that I installed Linux on, overwriting Windows. I am currently trying to reinstall Windows 10, but I'm running into some issues. My installation media is a bootable USB created using these instructions.
When I attempt to partition the hard disk and click Next to continue with the install, I'm greeted by the following error message:
We couldn't create a new partition or locate an existing one. For more information, see the Setup log files.
I've tried wiping and repartitioning the disk and manually partitioning it with
diskpart. I tried creating an ESP of size 500 MB instead of the default 100 MB. I also noticed that the USB drive was getting assigned the letter C, so I removed it, assigned C: to the primary partition on the disk, and reinserted the USB drive as described here.
So far, no dice. I did manage to grab those log files, though I can't make much sense of them. It seems to me that it can't find the EFI System Partition, but it should be creating one.
I have seen a proposed solution that involves copying the installation files to a partition on the disk, but this seems to only be for MBR. Is there any way to do this on a UEFI system?
To clarify, as per @Ramhound's request:
- The disk was wiped several times, both by deleting partitions in the GUI and by using the
- The disk has been formatted as GPT. Is there anything else that would be necessary for UEFI support?
- The firmware has been set to boot in UEFI mode, not Legacy Support mode.
Further system details: This is a Lenovo Y40-70 that originally shipped with Windows 8. Firmware is InsydeH2O.
