Can I do that?
or do I need to erase the partition, format it to exFat, and then install Leap 15.3.
I want to keep Windows 7.
Ya’ll see any problems? Do I need to disconnect the current Leap 15.3 hard drive? And can I bring it back to retrieve things on it if needed?
/dev/sda/ is a PATA drive ona a pci card.
/dev/sdb/ is a SATA drive connected via the motherboard.

Partition table entries are not in disk order.

To proceed:

  1. delete sdb2
  2. create appropriate size primary partition sdb2 for 15.3 / (adjacent to sdb1)
  3. create logical swap partition for 15.3 (adjacent to new sdb2)
  4. create logical partition using remaining space for 15.3’s /home (adjacent both to new swap and to 80G type 7)
  5. repair bootability of Win7 using Win7 installation media, assuming Win10’s bootloader was handling booting of Win7, probably unnecessary otherwise
  6. install 15.3
  • A user-friendly partitioner will automatically take care of moving the start of the extended partition, making the process automatic and transparent.
  • A premium quality partitioner will enable a reordering of the table entries in logical order as an option
    , the result being extended sdb3, swap sdb5, /home sdb6, Win 80G sdb7, and Win7 sdb4. Without selecting the option, Win7 would remain sdb3, the extended remain sdb4, and the entries remain out of order.
    Whether the partitioner within the 15.3 installer can do everything on the two lists I can’t be sure, but I would expect it to at least do the delete and move and creates, if not all. Key here is the extended must occupy a contiguous block that has no primary interposed, even if some freespace remains between the new sdb2 and Win7’s partition.

BTW, what card you’re using for PATA WDC WD1600AAJB-0 ? (lspci may help)

I’ll get to responses to this after I am sure I am not going to more hospitalizations this summer.
