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 :

enter image description here

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)

enter image description here

After that when i boot from UEFI on the USB Drive i get this error :

enter image description here

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?

Thanks.

  • Is it a 32-bit windows 7? 32 bit does not support GPT. – Bhavya Gupta May 11 '20 at 4:56
  • Also, you must disable legacy boot. – Bhavya Gupta May 11 '20 at 4:58
  • @BhavyaGupta it is x64 and i've already tried to disable legacy boot and use uefi boot. it does the error above in the black screen i mentioned. – Amr SubZero May 11 '20 at 5:12

If you're using more partition than MBR supports, you'll lose data, it is inevitable. MBR's limits are:

  • 4 primary partitions,
  • 2TB disk size, max

Switching between GPT and MBR without data loss, well, there're a lot of programs out there. You can use for example "minitool partition wizard" for that purpose. I don't guarantee that'll work for you.
