Is recovery disk a genuine OS installation disk ?

[krv5vignesh]

i have a HP p077tx notebook. I am supposed to make recovery disk from an already existing recovery partition. My question is can i make a clean install of my OS ( deleting the whole harddisk ) or does this disk needs a local storage of my recovery on my harddisk ?

All Windows 8/8.1 computers come with a restore partition. I highly advise you to buy a 16GB or 32GB USB flash drive and convert that restore partition into a reinstall flash drive. After you've made the recovery flash drive, you can delete the recovery partition on your drive you if you want to reclaim the space. (You can then extend the size of your existing Windows partition.)

If you don't like the default recovery partition state (maybe too much crapware installed), you can re-create the recovery partition after you've uninstalled the crapware.

Finally, if you totally screw up, you can still create a Windows 8/8.1 recovery flash drive by using your Windows key and downloading the 8-16 GB recovery image from Microsoft. Since you can do this even if you didn't make a recovery flash drive, you don't really need to do the first step I suggested. However doing so will save you the 8-16 GB download.
