That's usually a sign that Mint was booted in the opposite mode that Windows was installed to the disk in. If Windows was installed in BIOS/Legacy/CSM mode, but the Mint disk got booted in UEFI/EFI mode then something like what you described frequently happens. (Same thing if situation is reversed: Windows in UEFI, Mint in Legacy.)
Easiest way to tell which mode Windows was installed in is by looking at the partitions in Windows Disk Management. Look for a small (200-550MB) partition, formatted as FAT32 usually near the beginning of the disk, possibly labeled as "EFI System Partition" or something to that effect. (It will be a small
FAT32 partition; not a small NTFS partition, which may or may not also be shown.)
If that partition exists, then Windows was installed in UEFI/EFI mode and you need to make sure the Mint disk is booted in that mode too. If you don't see it, then Windows used Legacy mode and you need to boot Mint in Legacy mode.
(
One other note: If Windows was installed in UEFI mode, you
must use the 64-bit version of Mint as well as booting it in the same mode. If Windows install was Legacy mode, then does not matter which Mint you use -- 32-bit or 64-bit.)
Once you find that out, go into the UEFI Settings/Startup Menu and/or the Boot Menu and select the appropriate choice to boot the DVD/USB -- there will be two mode choices to pick from. Installation should work properly from that point on.
P.s. As others have said, make backups of anything important before installing. Also, make Win 7 recovery disks if you haven't done that already.
