Boot .dat file
I foud a file in my root directory called "boot???.dat". The three "???"
was three letters I can't remember. I installed on another partition windows 10. I erased windows 10 and windows 7 didn't want to boot. I ran my win 7 installation and there was a CLSID key in the registry that looked like it might be deciding default windwos OSes. I also have linux in another partition. So does anyone know the file I am talking about? Is that something windows 10 would put into windows 7 root ? Windows 7 learning it is a pain and an adventure. Bill |

Bill Did you install Win7, then Win10, then Linux, then delete Win10 ? That's the only part of this story, that would take zero work to get into such a situation. And you couldn't have entirely used the automation in each case, unless you Installed Win7 in automatic ("I don't care") mode Enter Disk Management and "shrink" Win7 C: to half size. Install Win10 in automatic ("I don't care") mode Enter Disk Management and "shrink" Win10 C: to half size. Install Linux slash as the next partition (could be Extended/Logical). That's about the least amount of work. Can you post a picture of Disk Management from when it was working ? An alternative, is to boot Linux and install the "disktype" package, a very small package. Then, sudo disktype /dev/sda and copy/paste the information into a new posting. That tool will tell us what partitions are present. When you also tell us the total disk size (available from sudo fdisk /dev/sda and the "print" option), I can then figure out the size of the "hole" where the Win10 used to be. Maybe. In theory, you could put the Win10 partition back, using TestDisk (from your still-bootable Linux). But that's more trouble than it's likely worth. TestDisk is a royal pain to use. In any case, a "multi-booter" person keeps backups, right ? You're never more than one step from a disaster when you do stuff like this. That's why we have backups, and we keep multi-boot partitions small so the backups won't take quite as long. Don't store your 1TB movie collection in your Win7 Downloads folder etc. Store it on a separate disk that can't get damaged by the "experiments". Paul |

[...] Yeah I have backups of my data. Online and on a USB if I am going to delete a partition. I installed win 7. Then shrank and created two partitions. I installed linux and then on the 3rd partition decided to try and install 10. Ten didn't take long to install. I was suprised. I seem to like windows 7 better though. I believe I deleted 10 while in linux. I don't know you could do it from windows 7. Windows 10 wanted to repair itself. Interesting setup there. So I rebooted by the wind 7 install disk. repair disk wouldn't do it. And used "fix disk" and the registry entries were changed. So I learned some interesting stuff there in this proces. I was given the options as to booting into 7 or 10. I didn't reinstall grub over this and put in an option for windows. IDK how that would've worked. I have learned many thigns from this. And sometimes it has involved losing data. But what's important I have online backed up. I have found a reinstall is sometimes only the real way to get rid of some things. You know these days it's hard to tell what they put on our machines. Windows 10's booting system intrigues me. It must involve the registry. Bill |

I have a "one movie" movie collection. in your Win7 Downloads folder etc. Store it on a separate disk that can't get damaged by the "experiments". Paul |
