Remove Ubuntu from Dual Boot

Uninstall Linux from Windows 8 Dual Boot

Linux is a great OS, which is not only free, but also open source. Although it is a great OS, but not everyone is comfortable with it, mostly the computer users who feels Windows is perfect for their use. However, if you have installed Linux on your Windows 8 Laptop you might be willing to Uninstall it from your laptop PC. Reason could be anything, you may want to free precious space allocated on your system for Linux or you may just didn’t like it.

Whatever the reason may be, here is a guide on how to uninstall Linux from your Windows 8 dual boot along with GRUB boot loader. Learn more about GURB in Ubuntu’s official website.

To do this we need to remove the partition in which Linux is installed.

Note: Create complete backup of data before proceeding. If you delete any other partition accidentally then you won’t be able to recover it.

Step 1: Boot into your Windows install.

Step 2: Type diskmgmt.msc and hit enter to open disk management or search disk management and open it.

Step 3: Once you are in Disk Management window, find Partition on which you have installed Linux.

Note: Be sure to find the right partition as Windows cannot detect Linux partition. It should usually be in ext3 or ext4 format.

Step 4: Once you are confirmed that you have found the Linux installed partition, right click on it.

Step 5: Now select “Delete volume” from the options. If you have more than one Linux partition then delete them by right clicking on it and then by selecting Delete volume.

Step 6: After deleting the partition, you can use that free space according to your need.

Although you have deleted the partition, to complete the uninstalling process you should also remove the Linux GRUB boot loader. Follow these steps to do the same.

Note: You have to create USB recovery Media by booting into your Window 8 Install. Follow these step to do it.

Step 1: Insert a USB drive into your computer.

Step 2: Type recoverydrive.exe on start screen to open Recovery Drive window.

Step 3: Click on Next, and select your USB drive.

Step 4: Click on Create to initialize the process.

Step 5: Now restart your PC with the Windows Recovery media select as first boot device.

Step 6: Once Windows setup loads up, select Repair your computer option.

Step 7: Select Troubleshoot from the Choose an option page.

Step 8: Select Advanced Options.

Step 9: Select Command prompt and enter following command.

bootrec.exe /fixmbr

Now restart your system. If everything went right then Windows should boot up normally without showing any select boot option.

Intel Unveils Its First Eight-Core Desktop Processor

Intel has unveiled its first eight-core desktop processor, the i7-5960X Intel Core Extreme Edition processor, alongside two new hexa-core offerings, all members of the product family formerly named Haswell-E.

"We're thrilled to unveil the next phase in our 'reinvention of the desktop' we outlined earlier this year," said Lisa Graff, Vice President and General Manager, Intel's Desktop Client Platform Group. "This product family is aimed squarely at those enthusiasts who push their systems further than anyone, and we're offering the speed, cores, overclocking and platform capabilities they have asked us for."

Clocked at 3.0GHz, with a 3.5GHz Turbo Boost mode and 20MB cache, the Core i7-5960X is priced at $999 (approximately Rs. 60,000). Aside from the i7-5960X, Intel announced two hexa-core (12 threads) processors, the $389 (approximately Rs. 23,500) Core i7-5820K, which runs at 3.3GHz (Turbo Boost up to 3.6GHz) and the $583 (approximately Rs. 35,00) i7-5930K, which runs at 3.5GHz and Turbo Boosts till 3.7GHz. Both 6-core offerings come with 15MB cache.

At the heart of the new CPUs is the X99 chipset that comes with support for DDR4 RAM, up to 40 PCI Express 3.0 lanes, 14 high speed (6 USB 3.0 + 8 USB 2.0) ports, Gigabit LAN, and 10 SATA 3.0 ports. The platform is also Thunderbolt 2 ready, which means manufacturers can add Thunderbolt 2 support via an additional card.

"I'm ridiculously excited about Intel's new platform," Kelt Reeves, President of Falcon Northwest, while commenting on the launched chips. "This is the biggest bundle of amazing new technologies all hitting at once that I can ever remember seeing. Enthusiasts will be amazed at what they can do with DDR4 memory, 10 SATA 6GB ports, 40 PCI Express lanes and eight-core CPUs."

Recruitment in Google via coding competitions

Google India has changed the way it recruits from engineering colleges, trashing paper-based tests in favour of Google Jams or coding competitions. Candidates will now have to crack coding puzzles online to clear the first few rounds of the placement tests at the coveted firm. Code jams are a popular method of hiring globally.

Google too has conducted them in India, but only as part of its global recruitment process.

"It has proved effective in candidate selection before the interview stage," says a company official who does not wish to be named.

The online testing platform, he added, gives Google scope to evaluate a large number of students from select universities.

Students are excited at the innovation. "My algorithms will do the talking," says Pranav Ramarao (21), a computer science student at BITS Pilani, Hyderabad. He won a Google Code jam contest in Hyderabad last year and was taken to the company office for a day. "You can immediately assess how good your code is unlike a pen-and-paper test where you don't know if the code is correct. They test your algorithms and data structure," he explains.

At least 50 students will be attempting the code jam from the institute's Hyderabad centre this month.

Google India has given top engineering colleges (non-IITs) four placement slots. "We do not have to sit in an examination centre and take the test. We can be part of the Google jam even from our hostels," says a student from NIT Warangal. At least 90 out of 120 computer science students at the institute will take the Google code jam this year, says a placement team member.

Google India refused to reveal its hiring target or the number recruited last year. "Our students are placed globally so we do not recruit them keeping location in mind," adds the official quoted earlier.

Configuring an OpenGL Development Environment on a Windows PC

Download and install Dev C++ (contains the Gnu C++ compiler and linker plus the gl.h and glu.h header files)
Copy glut.h to the C:\dev-cpp\include\GL directory
Add the following to the end of your computer's PATH environment variable: C:\dev-cpp\bin
(Do this by using the Edit feature at Settings | Control Panel | System | Advanced Tab | Environment Variables button | System variables window)
On your storage media of choice, create a directory called Demonstration
Copy glut32.dll to your Demonstration directory. (Note: The other two DLLs used by OpenGL, opengl32.dll and glu32.dll, should have already been placed in the C:\Windows\System32 directory on your computer when the Windows operating system was initially installed)
Copy build.bat to your Demonstration directory
Copy opengl-demo.cpp to your Demonstration directory
Start up a command shell by using Start | Run | cmd
In the command shell, change the current working directory to the Demonstration directory
Enter build opengl-demo.cpp on the command line. The program should compile and link with no error messages
Enter a.exe on the command line. (This is the default name of the executable file.) A graphics window should appear on the screen
After the color changes have stopped in the graphics window, click on the X in the title bar to close the graphics window. Then enter Ctrl-C in the command shell window to terminate the program and get the command prompt to reappear
