Good and bad news, I was able to use startup repair but it said it cannot repair my computer.

The Startup Repair log said the root cause is No OS files found on disk.

Repair action: Partition table repair
Result: failed. Error code= 0x3b92
Time taken = 2230ms

Something else I notice:
Quote:
Volume 6 G WinUSB NTFS Partition 3859MB Healthy
Is this your flash drive?

Mine looks like this:
Quote:
Volume 5 D FAT32 Removable 7690 MB Healthy
This is my entire readout:
Quote:
Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 F DVD-ROM 0 B No Media
Volume 1 C Windows 7 NTFS Partition 119 GB Healthy Boot
Volume 2 FAT32 Partition 100 MB Healthy System
Volume 3 E Data NTFS Partition 488 GB Healthy
Volume 4 G Video NTFS Partition 1374 GB Healthy
Volume 5 D FAT32 Removable 7690 MB Healthy

Volume 0 F DVD-ROM No media
Volume 1 C Data NTFS Partition 138GB Healthy
Volume 2 D Entertain NTFS Partition 393GB Healthy
Volume 3 E Recovery NTFS Partition 25GB Healthy
Volume 4 SYSTEM NTFS Partition 200MB Healthy Hidden
Volume 5 OS NTFS Partition 140GB Healthy Hidden
Volume 6 G WinUSB NTFS Partition 3859MB Healthy

Volume 1 and 2 is my logical partition. 3 is for the Asus Recovery partition. 4 is the EFI partition. 5 is the Windows partition. 6 is the flash drive.

It is strange since on my current PC, it said that the flash drive is FAT32.

That doesn't sound good.. Do you think you may have overwritten the OS while trying to install Ubuntu?

And one more question, when you tried to install Ubuntu, did you know you had a UEFI system?

Your Diskpart readout shows a 138 GB and 140 GB partition (hidden). Possibly the hidden one was from Ubuntu, but which one do you feel is your OS partition?

If you installed Ubuntu in MBR mode, on the same GPT drive you had Windows 7, I may try to duplicate and see what happens. You might think about using Partition Wizard, or G-Parted from the "Try" install of Ubuntu to look at your system. Maybe Ubuntu hid the Windows 7 partition and Partition Wizard could unhide it or straighten out your drive. I will know more after testing.

I will stop for a while so we can get back in sync, but you can't have logical partitions on a GPT drive..., at least not in Windows? Maybe that is messing you up.

edit: Partition Wizard may be able to convert your logical partitions to primary. Since you can have as many primary partitions as you want on a GPT drive, it should not be a limiting factor.

No, I don't think so. I use VistaPE (Windows Vista running on a DVD) and use a software to open the volume 5 partition: the Windows folder and other files are still there.

No, I did not. If I was, I wouldn't have used EasyBCD.

I'm sure that the hidden one is the OS partition.

Ok. I will use G-Parted to unhide the partition and get back to you. By the way, thank you very much

Volumes and Partitions are not the same thing.
Can you list partitions and post output ?

diskpart
>sel disk 0
>list par

And unhiding is just changing the id of partition
>sel par # - # is partition number
>set id=07 - NTFS
>set id=17 - NTFS hidden


And for transferring .iso to USB I would use "Windows 7 USB DVD Download Tool".

The more I think about it, the possibility of the Logical partition causing a problem is a good conclusion.

Your flashdrive showing as NTFS, when you show it being FAT32, plus the Hidden Partition, and other things.

I would use Partition Wizard, the Home version, bootable which free, and remove any partitions placed on the drive by Ubuntu. Then use it to change your logical partitions to primary, or just remove them also if you can.

I am currently installing the test bed....

I have just use GParted to find out about the partitions. There are strange things:
  1. The OS and the Recovery are not hidden as their hidden flags are not set.
  2. There are two boot partition: the 200MB EFI system partition and the OS partition.

Here are some info of the partitions:




I don't know what to do next. Hide the OS partition and then unhide it ?

Sorry, I had to edit a response. I suggest removing just the partitions placed on the drive by Ubuntu. And converting the logical ones to primary.

Logical partitions have shown some problems when dealing with UEFI
