Windows 10: Linux booting problem after creating another partition

I installed Windows 10 and after that I am unable to log-in to PeachOSI Linux. I had two partitions on a 350 GB HDD - 75 GB on which there is PeachOSI Linux and plenty of apps and rest space as Data partition. However I created another 75 GB partition to install Windows 10 1803, office suite and many apps. Since that moment I have been unable to log-in to Linux partition again. Currently I cannot boot up either Windows 10 nor Linux. Bootice and reinstalled MBR did not work as well. I received NTLDR Missing error. Help me to solve this booting issue.

How to go about building a tri-boot system?

i dual boot all the time, and going in to tri boot is easy.

step 1) partition the drive in to 3 partitions ( leaving 1 empty for the linux installer. )
step 2) install windows on the first 2 partitions.
step 3) install linux, and let it auto partition the remaining space. ( i recommend at least 30gb of space for linux, because it will make things a lot easier. )

step 4) enjoy.

 

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

Yeah, but he's throwing OS X in there. Not quite as easy to do, but not all that hard. Manual configuration of GRUB is necessary.
