I Have ideapad 330 15IKB Laptop with GPT Hard Drive and i'm trying to install Windows 7.
I tried to install it with Legacy Boot from BIOS configuration, but it failed to read the Drives/Partitions while installing. with error :
with some searching i figured that i need to use UEFI boot from BIOS.
so i used Rufus and created a Bootable USB with Target System: UEFI (non CSM) and Partition Scheme: GPT and File System: NTFS (the only choise)
After that when i boot from UEFI on the USB Drive i get this error :
By knowing that i have Secure Boot: disabled in BIOS.
i also tested lots of Windows 7 ISO original copies and i get the same error.
i tried to copy \boot folder from \efi\microsoft to \efi folder
and extracted bootmgfw.efi to \efi\boot and renamed it to bootx64.efi. and also getting the same error.
Tried a CD copy of Windows 7 with Legacy Support: Enabled.
and i see the Drives/Partitions while installing, but the Drives are GPT and the CD copy is MBR so i will need to convert my HDD to MBR and i can't do that since i will have to wipe all my data on that HDD.
What causes this problem?
