If you have a large enough partition under Linux, then you could use an app such as "gparted" to resize the root filesystem partition of Linux to something smaller. Then, in the space left over, you could create a new partition for Windows. However, Windows does like to be the first partition (if using a UEFI partition scheme, then UEFI would be first, followed by Windows). Installing Windows to the new partition would work, but then you'd need to reinstall the bootloader in Linux (e.g., using a Live DVD or thumb drive) to get the bootloader back to something which understands Linux (installing a Linux bootloader will detect the Windows install and likely just offer that as a boot option).

It does get complicated, and there is a lot which can go wrong doing this. You really would want a backup first. Better yet, also work with temporary media at the start: Clone this drive to another drive (e.g., with dd), work on the new drive for partitioning, and then clone the edited new drive back to the original drive (if you can't use the edited clone directly, e.g., it is a loaner).

If you value what you have, then you must be very careful (or don't even attempt this). Even if you work on this daily there is a lot which can go wrong when manually shuffling partitions around.

Is this to be o the same physical drive?

Generally, you install Windows first, then Linux.

Installing Windows second, it will almost certainly screw up the Linux GRUB info.
Yes i have an old and only drive its supposed to be on, unfortunately there is no solution . Am I right ???

Thanks for the reply, The problem is I dont have any other drive to back my data up and second this method is kinda risky so Maybe ill have to stick with this

As an aside to the backup issue. If you sign up for a Google account/Gmail you automatically get 15GB of space on 'Drive'. I am not sure if you can utilize said from your OS, I am fairly sure it still works with Chromium which will load to Linux. One Drive would be another to consider, but I don't use it thus have no idea how much space (if any) they offer free.
15GB isn't a lot, but could be enough for you to back up your mission critical stuff while you work this out.
