As I was still able to boot Windows using Hiren's Boot CD, I could reinstall the bootloader using a tool called EasyBCD.

I know you won't like this, but, firstly, I would go to the manufacturers website to see if there is any update available to the BIOS/EFI. I have not seen this in ages, but I remember seeing it quite a bit around the time Windows 8 generation boards/laptops launched - It could be that your bootable usb stick is fully compatible but after the first boot, ...

From the manual for your notebook: "To enter BIOS setup utility, press F2 when the Lenovo logo appears on the screen while the computer is starting up."

From what you said i think that you used the entire disk to install Linux. That may be reason Grub fails when it try to load windows because windows may have been removed in the process. If you have installed Linux and windows in two separate partitions properly then If you want to get back access to your windows then here is something you should try. It ...

Yes, you will have an entry about Ubuntu operating system information similar to Windows 8.1

Or boot to Windows 8 and use a BCD editor to overwrite grub. You can also use windows start-up DVD to rewrite the BCD. I'm doing about the same thing, but I'm trying to get the metro windows boot manager... still can't get it off of the legacy text-style loader.

The easiest way to go about this mess, is to install Windows first, then install any Linux Distro afterwards. You can look at this article if you intend to add it manually,http://askubuntu.com/questions/528947/how-to-add-windows-8-entry-to-grub-after-boot-repair but the risk is if you mess it up you won't access either.

If you read this Arch Linux forum page, you will find that several people have had the same issue you have. The consensus seems to be that GRUB2 has problems booting off a logical partition. It is impossible however to make a precise recommendation in your case because you do not include enough info in your post. It would be helpful to have the output of ...

Enter BIOS (while booting your PC, press either F1/F2/DEL/ESC, or whichever button opens BIOS on your system). Now search for something similar to "Boot Menu" and select it. Now select the SSD as primary boot device.

I figured out the problem. The two appliances used different scsi controllers(Paravirtual SCSI and LSI Logic Parallel) Although it turns out to be our build issue 'cos the two machines were supposed to be the same but the moral is to double check the machine's configuration and include every mandatory driver in the kernel.

It seems like there is a problem with ubuntu's /etc/grub.d/30_os-prober file I could hide the grub menu by disabling it with GRUB_DISABLE_OS_PROBER=true but then I lost the other boot options. I could solve it thanks to this answer at askubuntu: http://askubuntu.com/a/552431/26067 There's a bug in os-prober that overrides the GRUB_TIMEOUT variable, ...

You could copy the files from /boot onto a USB drive, boot the broken system from a rescue CD, then mount the USB drive and copy the files over. As long as version and config are identical, this should work. Otherwise you will probably have to chroot into the broken system after booting the rescue CD, then reinstall from "inside" the system (reinstall ...

Here's how I was able to do it using Grub4DOS (last official build): Grub4DOS can boot iso images, so it should be able to do it for partitions. We'd want to map the iso partition to a new drive and boot from it with: title Boot ISO Partition map (hd0,7) (0xff) map --hook chainloader (0xff) But this doesn't work, the whole disk is getting ...

I finally got rid of the error. And to be honest, it's stupid. The problem actually was, that the /boot partition wasn't created, even though it was shown in the UI. It's still possible to get everything running with the guided partitioning, but when you're asked to Write the changes to the disk?, you need to go <Back> to see a detailed list of all ...

Ok so, I finally found a solution: it seems Windows completely messed up the bootorder. I used EasyUEFI (I couldn't launch UEFI Shell), and first tried to change the boot order. After reboot, the order had been reverted (by Windows ? I suppose). I finally disabled the Windows boot entry, and it worked. I really don't know what happened, if this is Windows ...
