[spi_ajay]

hello,

i have 1 tb harddisk with C,D,E drives..my OS is on C drive ,, i have created back up of all drives in external..i am reinstaling OS on C drive where i had previously win10 15014insider preivew.. i am getting rid of insider preview and get back to current branch version windows 10 through bootable usb drive.when installing custom fresh install i want to know what is better .. should 1)i just just click Next and copying files on C drive continuing instaling windows (without format ) or 2)format C drive first and then click next copying files with instaling windows.. 3)delete all drives C,D,E and make unallocated space single,format it and then recreate partition again and install on the C drive

i want to know which of the 3 options is best for reinstalling windows to have stable

if you are referring to going back to the current consumer version and not a previous build of of the windows insider version you will have to do a clean install. the recovery options in settings would be able to reinstall windows but it would only install whatever build you currently are using

when you say C, D, E drives do you mean you have your 1TB drive partitioned or are they all separate drives?

C,D,E are partitions and not separate drives..and please understand i am trying to go back to CB from USB fresh install.. just want to know if i need to format C drive or just click "Next" which will do copying files continuing windows installation.

it will format then install files. it will warn you first when you select the drive and the drives partition

so i need not touch D and E drives and format only C drive and install only there

correct, . if you want to be eatra careful you can always disconnect those 2 drives before doing the clean install to C

If you backed up all of your data and wish to perform a clean install, and you had all of those unnecessary partitions (Why did you have them?). If I were you, i'd delete all of those partitions, and only create one for the operating system.

i thought 1 TB is huge just to create single partition, i kept movies, serials, tutors entertainment etc in D and E drive.. thts why i asked if i leave untouched and installed just formatted C drive is iit ok ? .. will formating C drive only can be called as clean install ?

You don't need all this partitioning. Why complicate things? But yes, to answer your question if your OS resides on c, you can format c, then tell windows to install the os on that partition. When you format a partition/drive then proceed with the install that is known as a clean install.
