Win 7/Win 10 Multiboot Issues
Dell Precision M4700
Internal SSD: Win 7 Enterprise (Bitlocker)
Internal Hard Drive: Data (Bitlocker)
eSATA: Win 10
I have a Dell Precision M4700 work laptop with Win 7 Enterprise (Bitlocker) installed on a SSD. I use an eSATA hard drive with Win 10 for my personal use. I have been having an issue with the WIN 10 updates. Everytime Win 10 has an update, the computer hangs up and will not boot to Win 10 until I run the repair. Win 7 on SSD has not been affected by this since it is on a different drive. But this last update to Win 10 caused issues. Even after a repair, I could not get Win 10 to boot, so I used a system restore. In this process, it performed a disk check and corrected errors. After the disk repair, Win 10 loaded fine, but when default booting to Win 7 SSD, after the Dell logo comes up and lists the drives, it just displays a black screen with the cursor and nothing happens. I sent it to IT dept and the boot sector had to be redone.
I have two questions:
1) Why would Win 10 affect another operating system on a different drive?
2) How do I prevent Win 10 from affecting Win 7 drive?

When you install Windows, it always replaces the existing boot loader with it's version. If you install the 2nd OS after you have removed the other disk, it can't touch that other disk and it will work fine. Once both disks are back in, you need to use the BIOS to select which disk comes first, and then it will boot directly to the OS on that disk. If you want to boot to the other disk, just change the boot disk to the other one in the BIOS.
