Hello, I would like to apologize in the beginning for my bad english, I hope you will understand my problem ! So I have this Lenovo y510p laptop, with windows 8.1 installed on it and everything worked fine until two days ago, when I tried to install ubuntu. I succesfully installed ubuntu and after few minutes of using it, the image freezed and I tried to restart the machine. After I restarted the machine I noticed that my OS won't boot anymore, so I tried to manually select it in the Boot Menu. Unfortunately, I received these errors : "Windows Boot Manager boot failed", "Windows Boot Manager boot failed", "ubuntu boot failed". Ok, so I started searching different solutions on the internet and I also tried a few things :
- I tried to repair my laptop using the Windows 8 installer, I selected Troubleshoot Menu, and I selected "Refresh your pc", and I receive this : "The drive where Windows is installed is locked. Unlock the drive and try again". After that, I selected "Reset your pc" and I received this : "Unable to reset your PC. A required drive partition is missing."
- After these try-outs, I decided to check if I can make a new installation of Windows, and I cant, it says : "We couldn't find any drives. To get a storage driver, click Load driver.". So now I thought that it may be a problem with my hard-disk, I thought that my laptop wouldn't recognize it or something like that, so I accesed the command prompt and I used the command list disk, and it shows me just the size of the usb on which I have my windows installation, no other disks. After that I checked if my hard disk is being recognized in bios and it is.
Does anyone know how to approach this problem ? I really don't know what should I do, your help will be so appreciated. Thank you !
