Because the disk space that the virtual PC will need will be allocated before the system setup, and thus the host will not try to give space from the disk again. In that case, you can use the virtual machine with more performance by configuring the virtual disk as the Fixed Size. Suppose your host computer’s hardware could perform better, or your host disk’s write and read speeds could be higher. NOTE: Since the virtual machine installation interfaces are different in the 6.x versions of VirtualBox, select the recommended VDI (VirtualBox Disk Image) for the virtual HDD file type at this stage and click Next. Since you will set up a clean system from scratch in the Virtual Hard Disk window, check the Create a Virtual Hard Disk Now option and specify a disk size of 10 GB for the virtual system and continue.

Hence, it would be more appropriate to confidently configure the RAM size of the virtual machine as 512 MB. You may get Insufficient memory to initialize Windows error when you specify a RAM size larger than 512 MB for Windows 95.
