No Boot Option, Just AHCI (Asus A450LC)

Dear,

I just installing Win7 Ultimate 64-bit for the first time in my Asus A450LC.

First problem is:
Error: Windows cannot be installed to Disk 0 Partition 1. (Show details)
Details: Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GTP disks. Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS.
Based on this : Windows cannot be installed to Disk 0 Partition 1
I delete both of the partition and continue installation without having problem.

But, when installation finished then laptop restarted it can't booting to windows.
So, i check bios and see that first booting is in my hard drive.
I try to restart again, but still can't booting to windows.

In some forums, it tells to check HDD Option, and if it AHCI change it to IDE.
When in Asus bios it can see in SATA mode selection, but i just find AHCI, no other option.

How can i change the type of SATA from AHCI to IDE?

What should i do? there is something that i could fix besides HDD setting?

Hi AddRAM,

I've try it.
I go to boot option>>delete boot option(is to remove EFI) but there is new window that say "select one to delete". But it didn't show anything to choose.
I attached the picture.

You can also go ahead and try installing to UEFI since it is the future and offers certain benefits, so you know what it offers: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with. You also were apparently doing so when you got the error, which requires that you delete all partitions so the installer can reformat them in GPT format.

If you want to Bypass UEFI to Install WIn7 then you'll need to find the correct settings in BIOS to enable Legacy, CSM or similar. Then you'd boot the installer as a non-UEFI device from the BIOS Boot order.

Changing listings in Boot Order isn't necessary since you'll only be choosing the device to boot there, which in the case of an EFI install means choosing the UEFI DVD drive or UEFI Flash stick to boot them to install to UEFI, deleting all partitions during the install.

Hi, i still can't solve the problem.

I try to install win8.1 then windows can boot normally.

Huff, don't know what, every installing win7 it always can't boot to windows.

Or the probelm is in my win7 installer?
