I deleted my flash disk drive. There were many files and folders within it -- now they are gone. Don't throw away nor wipe it out first, that's the advice I often heard. The secret is, actually we can save those data -- this is called recovery or undelete -- with certain hardware or software. Fortunately, gratefully, there is the best recovery software on GNU/Linux we can use, that is Testdisk, that has a very high success rate and is able to recover my data. I managed to recover 100% of one of my important folders with it. Below I share with you how I use it. You can practice this either on flash drive, hard disk, or SSD. I wish you success!

Last night, I experienced power outage and my laptop has no battery when I was talking on Telegram Desktop on my Neon GNU/Linux operating system. When I turned my laptop on, my Telegram Desktop was in logged out state. It was locked by its own security system. But that means I cannot see chats & groups anymore. The ultimate thing is that my phone is broken so I also cannot access my Telegram Mobile account: I cannot read verification code sent by Telegram official. Fortunately, I managed to recover my Telegram Desktop successfully without phone at all by using my spare operating system in the same laptop. Perhaps you experienced an unfortunate state like me, so I share with you my recovery story below. I wish you can recover your account too!

This is a recovery tutorial about using GRUB prompt to boot an operating system inside a hard disk drive. GRUB prompt is a program appearing at screen with black and white color, while a normal GRUB bootloader failed to be installed. GRUB prompt is similar to bash command line, usually in Terminal, but it has special commands because it is actually also the bootloader. By using GRUB prompt you can boot an operating system manually inside internal or external hard disk drive in any partition. Later, by successfully boot a GNU/Linux operating system with GRUB prompt, you may install the GRUB bootloader from the operating system.

Today we will show you some 'old' video taken from youtube (thanks to Tru3m0sl3m) that show us how to recover Ubuntu Partition after installing Windows. This video practiced with Ubuntu Maverick and Windows 7, but I think that same way you can do in all version of Ubuntu and Windows OS over Windows XP.

This video shows that we don't need any extra program to recovery Ubuntu partition except Ubuntu booting cd it self, is this way quite simple or hassle ?, check this video :
