It is unclear from your message what exactly is happening: if your computer doesn't have disk storage, it cannot have Windows 8 or Linux.
Anyway, regardless of the unclear situation with your computer configuration, if you intend to use RAMDisk or any other software, you should:
- Put a disk into your computer (HDD, SSD, or any other compatible drive).
- Install an operating system on that disk.
- Download a RAMDisk software that is designed for that system. SoftPerfect RAM Disk is compatible with Windows only, so it cannot be used with Linux.
- Install the RAMDisk software on the disk and follow its manual to set it up correctly for your needs.
Please note: RAMDisk software is not a magical solution to be used in computers with no physical disks. Except for some rare highly-specialised devices, a disk of some sort is an essential component, and must be there for the computer to be usable. RAM Disk software is only a means of creating
additional disk-like storage in RAM.
Regarding cell phone questions, I'm afraid it is not the area SoftPerfect is specialising in.
