Question Strange situation

[purple44heart22]

Hello. I have a computer with Windows 7 on it, which had an administrator password on it but I removed it and then installed some programs, then I went into the bios and it was set to ATA in the bios but I tried to set it to AHCI and it wouldn't boot into Windows after that, it kept giving me a blue screen, then the option to start Windows normally or "launch startup repair" and I gave it "launch startup repair", but that didn't work either, I think it tried to repair it but I don't think it succeeded, then I went into the bios again and changed from AHCI to ATA and it let me enter Windows on a new restart, but now Windows asked me for the administrator password again even though I removed it and all the programs I installed disappeared, as if they weren't there or I didn't install them, it was practically from scratch, how do you explain this? What actually happened? Why did my installed programs disappear or how did they end up being deleted? Why is it asking me for the same administrator password again if I removed it before this error, before changing those things in the bios, from ATA to AHCI? How do I return to the initial state again? Or at least see what was deleted? Or how can I see what programs I had installed before? Or how can I recover my data, what disappeared? Or that I lost or were deleted after this incident? Thanks a lot and sorry for my bad english!

sound like you have more than 1 storage or os on thesystem.

Or at least see what was deleted? Or how can I see what programs I had installed before? Or how can I recover my data, what disappeared? Or that I lost or were deleted after this incident?

we certainly don't. if you don't know what you have

the start-up repair most likely used an old restore point as a "last known good boot" effort. it did not fix your problem of getting windows to boot, but it did complete the process.

so when you got back into windows it was back where it was when the restore point was created. no idea when that was, but obviously long before you made the changes.

you lose whatever changes you made (including data created) when it moves back in time with the restore point. nothing you can do there.

only thing you can do really is copy any data from a back-up and start over with the program installation and so on as you did before.
