Install windows on formatted dynamic disk without installation CD/DVD

listen me carefully because I am trying to solve this problem for past two days.

here's what happened :

/# I had running windows 7, with "maximum number of partitions" in windows. checked with disk manager.

/# I converted disk to dynamic disk and created a partition.

/# I run a bootable pendrive (DVD is not supported) and start installing windows 7. during setup it shows windows can't be installed on this partition, so I start formatting partition from there. I removed all partition, even system and recovery. { :( BIG MISTAKE }

/# Now, you may guess when i try to start , BOOTMGR is not found,

1. I tried installing again, but it showed error in loading system32/winload.exe and asked to insert my installation media , unfortunately DVD is not supported.

2. I tried network boot using serva but during setup I don't see any drives it asks to load driver. and there is no repair your computer option in during setup.

   • I downloaded sata drivers but no success even when i load drivers during installation.
   • I don't know how to bring back Repair Your Computer option.

3. linux can't touch the dynamic disk , I heard

4. Windows 7 live cd gave me the last hope, but it failed two times and it takes like 6 hours to setup.It fails by restarting and asking start windows normally screen ? I start it , then comes setup is loading services, then it says installation error please reinstall. maybe something can be done here

/# Possible solutions :

1. Any small live cd options , ms-dos or xp or win7 with diskpart functionality ?

2. Any way bring back repair your computer when doing a network boot ?

3. Any way to completely format hard disk so I can have a basic disk in which windows can be installed over network boot or a bootable flash drive ?

I am just a student who only knew how to install windows using setup, so believe me I have tried everything i can think off, every site I can visit and now only you guys can help me.

Last option for me is to take harddisk out and put it in my pc and do a format, don't know how to do that, though.

PS. I have another acer laptop and a desktop pc both with windows 10. PPS. I can't download more than 500 mb unless extremely necessary.

Laptop specs :

Sony vaio PCG-61113P

Intel core 2 duo inside

came with windows 7

Any help will be greatly appreciated.
