I was trying to install windows to a laptop without cd-rom. Anyway wine would have to run the installer only until the first reboot(copy some files and install mbr).
Would not work. 1) Windows installer would be unable to load its drivers 2) Windows installer would likely be overwriting Wine files, big no-no 3) Wine would not have write access to MBR without serious security hazards (not to mention you don't need Windows bootloader in MBR to boot Windows) 4) Wine cannot reboot your computer
The only solution to your problem, without some external boot system such as PXE network booting or an external CD-ROM drive, is to use a VM, then extract the data as required from the VM and dump it in appropriate places on your real HDD.
