what do you feel if you experience an operating system damage due to a virus or software error, maybe all your work is interrupted, for example you are using a surfer esteem, then suddenly your laptop or computer has operating system damage, to be honest this is very annoying all Our activities are extinguished due to damage to the operating system, and what sucks again, passwords or other important data we are on the hard drive that fails to boot,
do you have a solution to overcome these ???
if you already have a solution it means you're good !!!
if you don't know yet i will give you a little solution, if you are experiencing this: D
the first step you have to do is your friend's house, to ride the Hirens Boot CD iso, I suggest your friend's laptop must be free of viruses, if your friend's laptop is using an antivirus eset NOD32 or 64, because in my experience, I make a rescue usb always successful , and safe from viruses, I have never tried other antiviruses ... but according to information my other antivirus friends still penetrate the shortcut virus: D
the second step you have to download ultra iso software. after downloading then install, after the installation is complete, look for the downloaded hbcd iso file then the ISO file we mount the virtual device / drive, after mounting the drive we open the file and we execute the HBCD file menu
after the HBCD menu opens, follow the image steps, open the partition / boot / MBR tab, look for the Grub4Dos menu tab, then install your flashdisk, how you can see the picture
ok after installing grub4dos on your flashdisk, please copy all HBCD ISO files to the flash disk installed Grub4dos
after that please try it on a laptop that has a damaged operating system .... if you succeed, you have the first aid rescue flash drive
good luck, greetings from me
