View Full Version : Lost my Windows parition? or recoverable?

So after using Linux Mint via dual boot on my Acer laptop (Win 7) over the past year and loving it, I got the bright idea to install ubuntu (64 bit) to my Acer desktop. Everything went fairly smooth.....except.....I have a feeling I made a really bad mistake and I'm hoping someone can help me walk through what I need to to do to either:

a) recover the data on my windows partition (at a minimum)

b) access my windows OEM recovery partition (for a refresh/re-install)

c) find a way to get this ubuntu to dual boot (which I'm not hopeful for).

From some of my research thus far, I'm left with the bad feeling that I won't be able to accomplish option C, and of that's the case, I'm fine with that. However, at a bare minimum, I really REALLY need to recover my data on my windows partition if that the case.

The good news is that Ubuntu boots right up and works fine. However, no GRUB menu as I have on my lap. Instead, it just jumps right into ubuntu. More bad news is that I can't see any of my previous paritions (Acer OEM recovery partition, or my Windows 8.1 partition).

Can anyone walk me through where I should start?

Thanks.

The more times you boot the machine and use it, the less likely you are to recover data. If you have your Ubuntu (or any other Linux) Live CD or installation media, boot it instead and run the command below to check to see if you have any windows partitions:


sudo fdisk -l

If you see any ntfs partitions under the Filesystem column, you should be able to access the partitions.
Do you remember which option you selected during the install? Did you install Ubuntu to the same partition as you previously had Mint on?

I actually never had Mint installed on this machine. That was on my old Acer laptop.

Before I installed ubuntu on this desktop, I created a separate partition from Win 8.1 for my ubuntu install. I believe I had three partitions when everything was said and done. A recovery partition, my Windows 8.1 partition, and this new ubuntu partition I created before I started the infamous ubuntu install.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file rename-ms-efi


=================== User settings
The settings chosen by the user will not act on the boot.

I don't know which option you selected during the install but, there isn't any sign of a windows partition in the bootinfo output you posted nor is there an entry for it in the Grub boot menu. Not sure if you can recover but you could try using testdisk. See the link below and be sure to read the step by step instructions before beginning.

Was Windows on Acer installed in UEFI boot mode or BIOS boot mode. You have Ubuntu installed in UEFI boot mode.
Reason is that Windows in BIOS mode only boots from MBR(msdos) drives, but UEFI uses gpt partitioned drives. And first question from testdisk is whether drive is MBR or gpt(GUID).

You cannot now recover working Windows nor recovery partition not some of your data. Linux install is small but writes full files all over drive, not like Windows NTFS where everything is packed into beginning of drive and then you have to defragment as parts of files then get written later on drive.

If deeper search in testdisk shows files be sure to copy to another drive immediately. If not then you need photorec which also is part of testdisk. Both are in repository, so you can easily install into live Ubuntu system installer.

You may be able to get new set of DVDs from system vendor for a nominal charge that would be the recovery partition. Generally the first thing you do with a new system is make backup of that partition. And have regular backups of your data.
