My new laptop came preinstalled with Windows 8. Naively, as I am, I just formatted the harddrive and installed fine old Ubuntu. Now I want to install Windows 8 for dual boot again, but I have no DVD and do download the ISO one needs a product key. That key is not on the back of the laptop anymore but somewhere on the mainboard.  Is there any way to recover the product key from the mainboard using Ubuntu?

I am trying to install a fresh version of Ubuntu in my computer without touching the windows 10 dual boot! In the Installation Type, the first option seems exactly what i wanted to do.  My question is, is this feature is safe to use? because i don't want to lose any windows files and other NTFS partitions on the hard-disk. Please eliminate my confusion. Note as that i dont need any files or media which are in the ubuntu partition, Thanks.

Actually, I have done something terribly wrong. I did not want Ubuntu 13.04 on my PC anymore. I was sick of dual-booting every time the PC starts, and I wanted to return to Windows as well. (My version is Windows XP MCE SP2). The mistake I did is that I simply used EASUS Partition Manager to delete the Ubuntu partitions. But what went wrong here is that, even when I did it, the GRUB keeps trying to load. It says that GRUB could not be found and finally ends up running GRUB Rescue.  I cannot "Repair" my PC using the Recovery Discs (containing Windows XP MCE), it only gives me an option to press "F", which will format the HDD to re-install the OS.  Although, the best part is that I can still log in to Windows. Because, when I boot from the CD's, it does not give me a "Repair" option, but only "Format" and "Quit". By using "Quit", it takes me straight to Windows.  But I do not want to keep doing this same thing every time I start my PC. Neither do I want to Format my Hard Disk. I have tried a few applications, like EasyBCD which do nothing. So I want a good solution for it.  Is their any way to install MBR through Windows or maybe Ubuntu terminal? Even if i can't access Ubuntu again? And what after installing Ubuntu again. Any safe method to uninstall it?

I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back?

I have two systems installed previously Windows 7 and Ubuntu. I was trying to reinstall Ubuntu and format the Ubuntu OS partition using a tool in Windows 7.   When I have Ubuntu ready on a USB stick and restart my laptop, it prompts me with the GRUB rescue screen. If I boot from USB to install Ubuntu, it just hangs.   Anyway, I messed up everything. So my question is how can I boot Windows 7 now?

My friend borrowed my laptop for a while and when he gave it back he said he replaced Windows 7 with Ubuntu. I asked him to switch it back simply because I prefer Windows. He claims not to know how. I don't want to go buy a new windows 7 disc I just want to figure out how to get rid of this Ubuntu and Windows 7. If anyone knows a way please let me know...

I have 2 partitions (Windows and Ubuntu 13.04) and I am asked which one to boot each time I turn on my computer.  I want to install Ubuntu 13.10 to the entire disk.  I do not mind if all previous Ubuntu/Win data are lost.  How can I do that?

A friend's Vista-based computer won't boot, so I am just going to format and reinstall.    The problem is that she never kept her product key for Vista.    Is there any way to recover that key from her hard drive (which is currently plugged into my computer as a secondary) without booting from it?

I booted from the Ubuntu ISO which I burned on a disk and installed Ubuntu, and chose the option to replace windows 7 with Ubuntu, now the version of windows 7 I was running was an illegal cracked version and I already had tried to get rid of it without booting into the actual OS and after many attempts was unsuccessful. Now did installing Ubuntu and choosing the option of replacing windows 7 actually solve my problem and did it wipe the previous windows OS EVERY LITTLE PART OF IT.

A virus has corrupted my desktop's hard drive. How can I remove the remnants of Windows and install Ubuntu on it?  I have only a working mobile phone and one 4GB USB drive. The 4GB drive has vacation photos on it. I have no friends to borrow things from. What to do? Step by step please, any terminal commands should be familiar to a Ubuntu user.  This question is loosely based on  which was deemed off topic by the DPP.

I am brand new to Ubuntu. I have just build my new PC, it has 2 separate hard drives installed in it. I would like to install Windows 10 on the first SsD (They are both 250GB Samsung 850 EVO) and i would like to install Ubuntu on the other and be able to choose to use either one or the other on dual boot. As i said I am brand new to Ubuntu. In fact, I have not downloaded or installed it as yet. I would like to know if this dual booting from separate hard drives is possible.

When I tried to boot my PC into Windows 10 I got a screen with a sad face saying unmountable_boot_volume.  After searching it said I needed a Windows 10 USB or CD which I do not have.  I still have access to Kali Linux on my PC by booting up with my SSD.  How can I make a bootable Windows USB with a ISO in Kali Linux OS?

I have a problem with Ubuntu 15.10  I have in my computer windows 10. Some days ago i decided to install Ubuntu in partition so i can have both in the same hard drive. The problem is that i cant get into ubuntu, i dont have the grub up so i always go to Windows in default mode. The only way to go into ubuntu is with the CD of installation, when im on the grub of the cd i press Esc, then i text exit in command lines and i go to a boot manager in which i can choose the ubuntu system. Its a strange think because it is the only way i can get into ubuntu, i will like to solve this problem. I try many tutorials already of solving this problem. I didnt get any solution so i will like to ask u before doing another tutorial. Thank u

I recently did a clean install of Windows 10, overwriting Ubuntu. How did Windows find out that I had activated Windows 10 before on my computer? It didn't ask me for a product key, but it is activated.
