error: no such partition. grub rescue
I don't think deleting all unnamed partitions from Windows is the right answer.
You should reinstall your GRUB to restore your boot menu. Check this question, it might be helpful.

I had multiboot windows 7 and ubuntu on my Samsung notebook NP305U1A-A07IN. I uninstalled Ubuntu by deleting all unnamed partitions from windows disk partitions as I read on net somewhere.
Now I guess Ubuntu is gone but i can't boot into windows anymore. Whenever I boot it says
error: no such partition grub rescue>
I know my windows partition and data is all there. Something is wrong with boot loader or boot manager.
As I have notebook it doesn't have DVD driver. But I have created USB stick of windows and Ubuntu too. But my BIOS menu can't recognize or load these sticks at all. I tried it on other notebook it works. But not on this one only. I even changed priorities.but it says boot override and shows two options only to boot hdd and network.
I checked a lot of forums and here too. But no solutions so far. I can't boot any USB stick so Windows command prompt solution from recovery is no use.
I have another doubt if these manufacturers lock BIOS to boot from another USB or DVD. But I installed Ubuntu from USB itself and now it can't detect any of those. I don't want to lose any data. Anything will work Windows or Linux now. At least let me know the way I can bring windows installation on it.

Samik almost 12 yearsDo you know in which partition your Windows installation resides? It may be possible to chainload Windows from that partition. As you have deleted your Ubuntu partitions the GRUB configuration file
grub.cfg
has been deleted alongside, which contains the OS menu entries you see on boot. -
netcoder almost 12 yearsThere's nothing you can do without entering recovery mode. If it doesn't boot from USB, try entering the BIOS, wait a few seconds and "exit without saving changes". I have similar issues on my Samsung laptop and doing this ensures it boots from the USB device (I think it needs a moment before the USB powers up after powering the computer). You may want to try different USB ports as well.

Samik almost 12 yearsThanks for pointing to that answer, but the process mentioned there involves booting from a Live Ubuntu CD (or Live USB), which, the original poster is unable to do. You may want to modify your answer in that perspective.
