Hello guys. I really need some advice here. I have a laptop Asus G73jh, it supports UEFI. Connected to it externally (through sata from the dvd drive port) is a WD 3.5" 3TB disk. This is formated in GPT NFTS just a single partition. Here i store all my music production software/libraries. I want to install windows 7 on this one seperately (dual boot) so i can use this disk exlusively for music production. I went past the point and finally made a Windows 7 UEFI usb installation disk. All good it will let me select the 3TB disk for installation. When i click next it will not let me continue with this: "setup was unable to create a new system partition...see the log blah blah". So i guess it won't let me install it in that partition (i'm not sure why? because it is NFTS?). Anyways i can't format the disk to a new partition since i don't have anywhere to copy my data. If the problem is it needs a clear unlocated space to make the partition i can shrink the one i have already using the free space i have. Can someone clarify what the hell needs more to install? Thanks!

Freezing at Windows Install

I've installed Windows 8.1 Pro X64 UEFI mode into my Asus K45A. But for now I want Windows 7 to be installed just like W8.1 is instaled by now. Fastboot and UEFI.

Well, I'm using Rufus to make USB flesh drive install..
It freezes right after Windows setup load up files... that white progress bar over a black screen...
When it appears Windows is Starting and Windows flags shows up... than it freezes.

I just tried it with:
Secureboot ON, Fastboot ON, CSM OFF
Secureboot ON, Fastboot OFF, CSM OFF
Secureboot OFF, Fast boot OFF, CSM OFF

All of these didn't work.

Just this conf worked out.
Secure boot OFF, Fastboot OFF, CSM ON.
But if I'm not wrong this conf will not install Windows 7 in UEFI mode.

So, what I'm doing wrong?

Proceed with the install to see.

Are there specific CSM settings to choose from, or sub-settings like UEFI First or Legacy First?

CSM doesn't necessarily preclude UEFI boot but there may be other settings to assure it. Look for UEFI boot, Legacy Boot, and under Save Settings tab see if there is a Save Optimized Windows 8 settings (which comes with some preinstalled Windows 7) or Save Default settings for using another configuration.

Did you use Option 1 in UEFI Bootable USB Flash Drive - Create in Windows

Proceed with CSM enabled?

There's no specific sub options after enabling CSM... but if Secureboot is enabled even enabling CSM and saving after reboot fastboot comes to be active and CSM disabled.

There're two options into boot options like my USB when CSM ON. One is for normal USB boot and other is for UEFI boot. I'd choose UEFI.

So. I Will try it with CSM ON and Secureboot OFF, fastboot OFF, usb UEFI boot option.

If CSM does not precule UEFI what CSM really is? :S

There's no specific optmized options. Only "restore to defaults" in setup (a.k.a. BIOS)

yes, I did use Option 1 but I'm trying it on the manually way too

About 10 minutes I'll come here to say what happened with my CSM ON attempt but I'm online right now to see any new answers

Secure Boot is only for preinstalled Win8, a marketing gimmick to convince business that it must migrate to 8 to protect against BIOS infections we've never seen here at the top tech forums. It failed miserably considering that business if moving off of XPiring to Windows 7 almost entirely.

So forget it and try the install with CSM. With some mobo's that's enough. If it isn't we need to look at your BIOS settings since they are all different, another reason UEFI is problematic crapware not worth the bother.

Yeah. Forget Secureboot. heehhehe By now I'm happy with my fresh Windows 7 install (: It worked
But I got one more question. What about fastboot? Fastboot is avaiable only if secure boot is on too?
All that's because I'm fastboot, if possible with my Windows 7. Because, for me, it's very very useful to have fastboot.
Is it a matter of drivers? Or because I used W8.1 + Ubuntu and both of them boot up faster. So I think. Why with Windows 7 should be different? Right? So, Is that possible?

Try Fast Boot to see if it works with CSM.

CSM is Compatibility Service Module which allows legacy BIOS functions. I don't think it should preclude Fast Boot but every mobo is different.

from page 1 of this tutorial, my hard drive does NOT form those 3 GPT partition. So win 7 won't install. How do you make win 7 form those 3 partitions?

In some details, I am working on a Toshiba ALL in 1 PC that c/w win 8. So I wiped all the partition on it and start off fresh.

I change the BIOS to non secure boot, and make the boot mode to CSM Boot

So win 7 boot up, and I'm at step 7 on page 1 of the tutorial

UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

Quote:
click/tap on New, Apply (for full size of disk), and OK. (see screenshot above)

8. You will notice that the disk has now been formatted as GPT with 3 partitions. Select the "Primary" partition 3, and click/tap on Next.
I don't see the 3 partitions. I only see win 7 formatted the entire in 1 big 750GB partition. So obviously win 7 won't install



Prior to that, it's all unallocated space
