If your computer came with an OEM genuine Windows 8.1 pro, there should be an embedded unique key in the BIOS. You can find the key using this open source software. then try to upgrade with this key.

You cannot. But the easiest solution is probably also the best. Use a windows 8.1 Pro install medium to perform an update. It will keep your settings etc in tact but change the version of windows. After that you will be able to activate windows. To perform an update, insert the cd while you are in windows and run the setup. It will ask you to update that ...

Go to Computer > Properties and see if you have Service Pack 1 Installed on your Windows 7. If not, you have to install it using Windows Update or the offline installation here.

Not sure what you mean, but if you take for example debian on X86 or ARM it will work the same. The binaries are not compatible because the CPU architecture is not the same and everything had to be recompiled. When you are only using OSS this will be no problem most of the time (unless the code uses X86 assembler and you want to compile it for ARM, for ...

Simply format the partitions of BT and re-run grub-mkconfig from Ubuntu. Unless you did make a more sophisticated install, this should suffice. If you want to also get back the free space, make a new partition and mount it or resize the Ubuntu partition afterwards. The latter might corrupt the fs though so be sure to backup before.

OS-Uninstaller is a small graphical tool to perform a clean and quick uninstall of any operating system (Windows, Mac OS X, Ubuntu, other Linux distributions..) of your computer. Download Boot-Repair-Disk. Then create a live USB of it with UNetbootin from the Ubuntu Software Center. Boot with it. A window (Boot-Repair) will appear, close it. Then launch ...

Your guest OS gets its clock from the host at boot, and this, hopefully, should keep the two synchronized. However, this does not occur, because intervals between timer interrupts (on which the OS bases its time keeping) are stretched and compressed by VMWare (and Xen, and VirtualBox, and HyperV, and...). You have two solutions. Either you use a daemon (in ...

You're using, per the tags on your question, Red Hat Enterprise Linux or CentOS. Since version 7, those have used systemd. As such: Forget about runlevels; they exist, but only as compatibility shims. The systemd documentation states that the concept is "obsolete". If you're starting to learn this stuff on a systemd operating system, don't start there. ...

If you are running Ubuntu as a Guest under VirtualBox then you should be aware that the system time is automatically kept in sync by the Guest Additions Your solution in that case is to disable the Guest Additions, which can be achieved by executing sudo service vboxadd-service stop or sudo /etc/init.d/vboxadd-service stop You can then set the time ...

PING -A xxx.xxx.xxx.xxx This will try WINS and then DNS. The NSLOOKUP command does similar, but only via DNS.

Although the official names are Windows 2000/XP/Vista/7/8/8.1, the Windows NT "version" of these releases are 5.0 (Windows 2000), 5.1 (Windows XP), 6.0 (Windows Vista), 6.1 (Windows 7), and 6.2/6.3 (Windows 8/8.1). Windows NT is no longer a part of the actual product names, and is indeed only used to refer/identify operating systems internally. This table ...

Yes, all newer Windows version (XP, Vista, 7, 8.x and now Windows 10) are based on the NT line. Servers were always NT line. The older 9x line was ended with Windows ME.

Is there a performance difference when installing an OS on the last partition? Yes. Enough of a difference to matter? Depends on what you're doing, but generally it won't. Partitions are allocated from the outer edge where sequential speed is higher. Later partitions will be closer to the center with slower sequential speeds. You can observe this with ...

This makes very little difference - indeed you probably won't notice it. The difference is not nothing, as typical hard drives are faster when reading the outside of the disk then the inside, but you probably won't notice the difference. If you are using an SSD there is no difference.

8-bit CPUs usually had a 16-bit address bus. (Motorola had a unified address bus, RAM and peripheral I/O shared the same address space, Intel chose to divide the two. In the case of Intel, the IO address limits of the 8088 and 8086 carried the limits over from the 8080 & 8085 CPUs.) Intel's 8088 and 8086 had a 20-bit memory address bus(1MB), while ...

Windows boot files are either on active partition in case of MBR disk or on EFI System Partition in case of GPT disk. A. In the case of UEFI boot and GPT disk you can delete the partition of the OS you want to remove without problem. A.1. If the OS to be removed is Windows - you have to delete also the corresponding BCD entry for loading that OS. A.2. ...

⌥⌘H will hide all other applications except for the current one. This is the Hide Others command, which can be found in the first drop down menu on the menu bar for the application (i.e. Safari menu for Safari). Switching focus to a hidden application, i.e. via ⌥Tab or clicking the icon in the Dock, will unhide the application.

"based on" means similar functionality. Linux is based on Unix because it aims to the same way of work. derived from means that it uses the same basic tools. For example, Ubuntu is derived from Debian. Ubuntu uses the same fundational tools of Debian adding some of their own.

The general steps in these cases are: Boot from a live CD Mount your linux partitions Bind mount /dev /proc /sys /dev/pts Chroot in the mounted system Re-install GRUB From crunchbang forum: http://crunchbang.org/forums/viewtopic.php?id=15351

These phrases mean the same thing they mean in other contexts, and they are just as subjective in this context as in others. If a new car model is based on an old one, then some part of the old design was used in some fashion, perhaps directly, perhaps modified, perhaps just as an inspiration, when designing the new one. If a fictional story is based on a ...

There are no strict definitions of the terms you describe, but what they often mean: "Derived from" often means a fork somewhere along an operating systems development cycle. Say, someone liked what Ubuntu had to offer, but decided to make their own version, and thus Linux Mint was born. "Based on" is a bit more loosely used. Many would say that Linux is ...

Under Linux, it's very simple for a program to arrange for a temporary file to be deleted when the program is finished with it, even if the program crashes, and this has been part of Linux since the beginning (and before: the open-delete-close pattern for dealing with temporary files has existed in most if not all Unix-like systems). In contrast, the ...

If you did an upgrade of an 10.10 install where everything still worked fine (and where the Apple-supplied java 6 runtime was installed), the following solution might work. I had the same problem as you had, and this solved my issues: Quit IntelliJ and go to the Applications-folder in Finder Right-click the IntelliJ.app and choose: Show package contents ...

I'm not sure how comfortable you are with the inner workings of a computer so I apologize if some of my answers seem a bit obvious. Does it have all the parts you need for it to run? Memory (you said you put in the sticks of RAM, so yes) Video Card (either a discreet card or built into the motherboard), connector will most likely look like this, or ...
