Failed ubuntu installation, windows won't boot

[jure]

Hi,

I tried to install Ubuntu on my Lenovo y580 and things didn't go as planed. It is the first time I am dealing with Ubuntu and partitions so I'm quite lost. I have Windows 7 Home premium 64 bit.

In short:

I deleted Ubuntu but windows doesn't boot. I have windows recovery dvd and Lenovo system recovery dvds. I tried bootup repair, but it says, it cannot repair. The errors are: 6.1.7600.16385, MissingOsLoader
I also tried different commands in cmd: bootrec.exe/FixBoot , bootrec.exe/FixMbr , bootrec.exe/RebuildMcd ,
I also cannot come to safe mode boot option.

Long description of what I did:

The laptop comes with 1Tb hard drive and small 32Gb ssd for caching and system. Since the system already had 4 partitions, I deleted the partition which is meant as a back up partition and I also shrank the storage partition -> got 2 pieces of undedicated space. Before that I made recovery discs and windows repair dvd. Sadly, didn't make a restore point.

Then I installed Ubuntu using LiveUsb. There was no option (in installation process) to install it alongside Windows, so I created new partition. Everything installed nicely but after that I could not boot Ubuntu. The computer booted straight to Windows. So I used Ubuntu boot repair. After that I could boot Ubuntu, but I couldn't boot windows. Than I used Ubuntu boot repair once more (I saw somewhere that it should help), but didn't help.

In the next step I deleted Ubuntu using Ubuntu os uninstaller and I also deleted the partition, where it was installed. I did that using LiveUsb.

Now windows doesn't start. I tried bootup repair, but it says, it cannot repair. The error is: 6.1.7600.16385, MissingOsLoader,..
I tried different commands in cmd: bootrec.exe/FixBoot , bootrec.exe/FixMbr , bootrec.exe/RebuildMcd ,
I also cannot come to safe mode boot option.

Thanks for help.

Hello,
From what I've read it sounds like the grub boot selector didn't come with Ubuntu. When I installed Ubuntu along windows it automatically came with a loader so you could select what one to boot,
Now to get this straight, were the two OS's on the same drive and separated by partitions, or are they on separate drives?

I figured out that partitions were totally messed up, so I used recovery discs and restored system to factory settings.
I would still like to install Ubuntu, but first I would like to figure out what went wrong. My system:
-32 Gb ssd which is divided into 2 parts. 24Gb part is visible to me, 12 Gb part is reserved for caching I think.
-Hard drive is divided into 3 parts: oem part, 200Mb system part and 900gb part for boot and data.
What I did: I deleted oem partition, shrank 900 gb partition, created new partition from one of the unallocated spaces ( I thought I could join those two unallocated spaces, but didn't know how to). On this new partition I installed Ubuntu.

If you install Ubuntu into a virtual partition using the free VMware Player, you will have none of these troubles and it runs just as well. Plus you have the added advantage that you can run Windows and Ubuntu side by side.

Here is a tutorial I made for Installing Zorin which is an Ubuntu derivative. Installing Ubuntu would go the same way. Only the commands for the tools would be different.

And this is a link to a demo that shows the advantages if you run 2 systems side by side - in this case the guest system is Windows 8 but it would work the same for Ubuntu.

And here is an example on how you install the VMware Tools - in this case I am using Mint Mate (the best Linux distro in my book)

The terminal commands I used for Mint should also work for Ubuntu, but I have never tried that.

Here is the best way to Dual Boot - Windows 7 and Linux - Windows 7 Forums

I would replace the grossly inferior factory pre-installed WIn7 with the best possible install one can have compiled in Clean Reinstall - Factory OEM Windows 7.

During the install be sure to delete all partitions on the disk as illustrated in Steps 7 and 8 of Clean Install Windows 7 so you have the cleanest slate with nothing to interfere. http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html
