Is it possible to create 7 boot partitions by editing MBR file ? No. When using MBR you only have room for four primary entries. You can not add more. What you can do is add an extended partition (which uses one of the three primary entries). Then you can create more partitions inside that extended partition. Alternatively you could use GPT setup, ...

Many modern operating systems do not need to boot from a primary partition. It sufficies to just use a boot manager. Even windows 7 and 10 can be installed for extended partitions. I ran windows 2000 of the h:/ and windows NT of a primary partition on the second hard disk.

I can think of a couple issues that may be at play here. First, you may have daylight savings time enabled in one and not the other, or one of your OSes is configured for the wrong time zone. Linux may be assuming your computer's hardware clock is set to UTC instead of local, and Windows may think it's set to local. If you're at UTC+1 or UTC-1, you may see ...

I suspect that your installer is not booting with EFI. In order to install Windows onto GPT disks, you have to boot the installer using EFI. EFI booting (and the related "CSM" boot options) are complex enough to write a book about, but the massively abbreviated version relevant to this discussion is that a Windows installer disc (or USB disk, etc.) can be ...

Other than being inconvenient I suppose, and that typically you can't have more than one bootloader on a drive.You pick a boot drive not a partition. So, on a single disk dual partition system? It simply would not work. You'd have to use the bootloader on the drive and pick an OS from there. On a multidisk setup with one OS per drive, it works pretty ...

Your linux distro is assuming your BIOS clock is using UTC, and your windows install is assuming that your BIOS time is in local time. Here's how I have it set up on my laptop with a dual-boot: I make the changes linux-side to use localtime instead of UTC for the system clock. first, run a command so that the time is set properly linux-side, as root: date ...

I have no definite solution, but I do have some observations and suggestions: Show us details -- Your summary of what you've done at every step omits an awful lot of details. What might be helpful is a summary of those details at one point in time, then stop messing with the system until you collect a few suggestions that you can prioritize. The Linux Boot ...

For mine, I have a couple more lines to load windows 7 than you list. The search with a hint and the parttool may be the missing pieces. menuentry 'Windows 7 (loader) (on /dev/sda3)' --class windows --class os $menuentry_id_option 'osprober-chain-0CF4A859F4A84734' { insmod part_msdos insmod ntfs set root='hd0,msdos3' if [ ...

Bit late for an answer (2 years) but anyway... you have to change the boot order in BIOS by pressing F10 at startup (not just via F9, despite what the menu suggests).

Just want to share my experience. We burn a lot of bootable ISO's to flashdrives to setup anything from Windows server series to Windows 7 through 10. We ONLY have issues with Kingston drives when it comes to this. I spoke to a guy at tech support from Kingston and after a lot of useless info it basically boils down to its not guaranteed to boot. So i tried ...

To include boot from CD in Windows XP/7 boot menu eventually look for "grub4dos". The method is called chain loading of another boot manager/loader. This method works only for BIOS firmware. (On UEFI firmware there are other solutions.) Grub4dos has its own configuration file where you can specify what device or OS you would like to load. Grub4dos allows ...

By grub shell I assume you mean grub rescue shell instead of normal shell. The reason is probably due to the fact that the "second drive" is not ready when the grub EFI binary on the ESP (which is on the "first drive") is executed by the UEFI, so the binary failed to locate the grub modules and grub.cfg (which is on the /boot directory of sdb3, if you don't ...
