Windows 10: Windows 10 doesn't boot up when delete other hard drive partition

Hello. My computer is an Acer aspire with SSD and HDD. Long time ago, i installed windows server on hdd, but deleted it away ( idk if it matter). Now, my Windows Education is installed on SSD. Yesterday i deleted some partition on the HDD and after a reboot, it show 0xc0000001 and 0xc000021a What i've tried: Burn a windows installer USB and: Use startup repair ( couldn't completed..) Use the system recovery ( it said isn't enable the some kind of protection) Use bootrec (fix mbr,scanos) The macrium rescue free love usb Bcdboot ( path of windows) /s ( the efi partition letter) The way to delete entire EFI, MSR and build a new one (http://woshub.com/how-to-repair-deleted-efi-partition-in-windows-7/)

I've even install new windows 10 on free partition on ssd to launch Easy BCD, but dont work. Is there any clue? Because there are some kind of software that doesn't allow me to reinstall, and i dont have the install package. Thanks and have a good week.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Delete my W10 Partition

Do you want to safely delete your Windows 10 partition and use only Windows 7?

If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :





Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.

 

2 of my internal hard drives, not been reconized!!

With both hard drives plug in ,I get to the page to where to install windows7pro , none of the disk are usable , ""windows cannot be installed to this hard disk space. The partition contains one or more dynamic volumes that are not supported for installation" Maybe if I tryed to install windowsXP and than do the rest that you suggested, (just a thought)
