Hello,
I'm trying to install Kali Linux on my vaio laptop. I tried an bootable usb, but after putting the external device as bootpriority it says 'bootmgr is missing, press ctrl+alt+dlt to restart' every time. Downloaded the iso again to make sure is wasn't corrupt and again the same screen. After this i tried putting the iso on a dvd, dvd as boot priority but it only starts windows.. seems to not read the dvd. After all this i tried something a friend told me, to run the kali linux iso while mounted in windows. I started with copying files and that's it. I restarted my laptop and now Kali Linux is added in the windows boot menu to complete the installation. So started the linux installation here, installation wizzard is searching for the cd so i put in the usb drive. I'm able now to make the needed partitions, but when trying to install the system it says it can't install.. (manual or guided partitions, no difference) Nothing else. When using the dvd intead of the usb it just says the cd can't be found.
To be sure it's not just my laptop i tried the same bootable usb on my desktop (already dual booted with kali linux and windows 7) but also got the missing bootmgr message while i installed it on this pc with the same usb device!
Now i found different topics about this problem on the internet, but everytime the talk about an system that already has a dual boot, or when just installed.. No one seems to have this before the install. Someone knows what the reason can be?
