BOOTMGR is missing

I have an HP ENVY 4t-1000 Sleekbook. It originally had Windows 7 Pro 64-bit. It was upgraded to the free Windows 10 around August of last year. In February of this year it error-ed out with "Bad Windows Image". Recovery Media from HP (usb) has been loaded onto the hard drive (drive checked good). In order for the SWM files to complete, the laptop must reboot, therfore no OS is actually on the drive and functioning. This is where the "BOOTMGR is missing" message comes into play. Is there a way to correct this problem?

Someone else might have a quicker, easier, or better solution. But you could try the boot repair tools in this free Paragon rescue kit. Would burn it to mem stick, boot from the stick, and try repairing from there. Good luck.

Do a System Restore to the last known good point.

If the hard drive had an OS on it, I could probably do the things ya'll mentioned. However, the hard has nothing until I load recovery data. It asks that a reboot is required to complete. When it reboots I get the BOOTMGR is missing. Just for giggles I loaded a copy of Windows 7 and it loaded fine with no problems. Tried the recovery media from HP again and still get BOOTMGR is missing. I'm at a loss on this one. HP wants my friend to ship the laptop to them for repair but they want way to much since it is out of warranty. Laptop came with no COA sticker. It was purchased directly from HP and they will not give a product key to just load 7. I guess my friend will purchase 7 from somewhere and I will install it for him. Oh well, just another bump in the road. Thanks ya'll for your response.

Before you invest in a new copy of Windows, or buy a new computer, try installing a Linux distribution such as Mint or Antergos. The Linux OS will likely recognize the presence of Windows, and you will be able to recover data and operating system as well.
