Computer: HP Pavilion dv7-6140eo
OS: Originally Windows 7
I recently decided to try out Ubuntu, and I decided to dual-boot it with Windows 7. First I googled some how-to's, then I downloaded Ubuntu onto a memory stick and made a second partition (I originally only had one partition that I shrunk and used the unallocated space to install onto during the Ubuntu install). During the install I set format type to xt4 (or something, it was the default option), chose the "in the beginning" option and set the last option as "\".
The install was successful. Although, when I restarted my computer I weren't able to choose which operating system to start; it went right into Windows. After showing the Windows logo for half a second before rebooting, I get a blue screen (see bottom of the page). Trying to fix it, I deleted the newly made partition I had just installed Ubuntu onto (seeing it wasn't working either). This made no difference. I proceeded with installing Ubuntu again, so I would at least have a functioning computer, and now Ubuntu works fine (I'm on it now). The only difference on start-up is that I get a GRUB window asking me to between several options including Linux and Windows 7 (loader).
Now, if I choose Windows 7, I get the message:
Windows was unable to start. A recent software or hardware change might be the cause.. It recommends me to choose the first option of the two it provides; to start start-up repair tool. The second option being starting Windows normally. If I start Windows normally, the same thing happens as earlier.
My computer does not have a Windows installation CD. Although, it has (at least it used to, if I haven't screwed that too up) a 17gb recovery partition. In addition I made an image of the computer onto a external hard drive when I first got it, though, I have no idea how to use either.
If anyone has any idea how I can make Windows work again or reinstall it (I already backed up my files) it would be greatly appreciated. I still prefer to dual boot between the two functioning operating systems, but I will settle for a functioning Windows 7.
