Windows repair disk: Invalid SO version.

The ASUS Shop app rejects my serial number... so I post a message to Asus support to see what happens and their answer is threre´s no repair disk available for my model I can't believe this.

You can make the Start up Repair from Windows.
System Repair Disc - Create

From ASUS you would order the ASUS OEM manufacturer's Recovery DVD's.

I borrowed a Win 7 Home Premium x64 SP1 , the latest version

At this point I learned my ASUS came with a GPT formatted disk. In fact, it's the first time I've heard of GPT

Are you booting the disk in UEFI mode?

Yes, that's what I should have done before trashing the BCD. No Windows now.

But I have that system partition intact, and access to all the files. I'm wondering how could I get info from there to figure what exact repair disk version he needs.

Tried with a repair disk creataed in another laptop with (apparently) the same SO version. Useless.
Tried with three different stages Win7 Instalation disk, with and without SP1, to use the embedded recovery options. Useless too.

I did, but their web rejected my order, and they told me it's because there is no Recovery DVD for this model. This was yesterday, still waiting for more feedback or explanations from ASUS support on this point.

I only have that option for DVD / USB booting, and not always. Depending on the boot media I use, some times I can choose, at BIOS boot menu, UEFI / Non UEFI boot. Don't know what makes the difference, actually. I'm using NON UEFI by default. is this OK?


Thanks for your answer!

You probably need a non SP1 version.

If tried three different Instalation disks, with and without SP1.

I'm afraid this must be a deeply customized OEM version by ASUS, as this is one of their "High end" machines.

Thank you, AddRAM

May be this workaround:

- Backup all partitions to external HD
- Convert the disk from GPT to MBR, then back to GPT (all partitions are los)
- Replicate the original partition structure
- Install win7 in his partition, so boot system is regenerated.
- Dump back original partitions, system included, overwriting the previous install.

Sounds ok to you?

I decided to go straight

1 Backup all partitions.
2 install a new Win7 64 SP1 on partition C: This restores BCD, but overwrites old installation.
3 Restore partition c: from revious backup.

BUT

At step 2, the install programs stops asking for controllers to access my hard disk.

This must be so because it's a GPT partitioned hard disk. Ive used the same Win7 USB on the same laptop with a MBR disc with no controllers issue.

And surely this is why no Windows Repair/instalation disc can handle with my sistem and the all say "invalid SO version".

I have three different USB sticks tha can boot and have perfect access to my hard disk. (Acronis DIsk Director, Acronis True Image and Wondershare LiveBoot. I've searched on those USB's the drivers they use, but cant find any. What to search for? Threre's no "drivers" folder. In fact, there are so few files there, i bet all drivers must be integrated on a compressed file or something so.

Any suggestion?

Use a UEFI mode DVD/USB.
