So that is the repair boot tool report about my issue, so i hope you will help me guys. https://paste.ubuntu.com/p/Tc7qs3QNwx/

More info. So i used chatgpt before and some others online tools so it see i must have a file /esp/efi/microsoft/ so i cant see the microsoft file, as i understand the boot windows file must be in this folder.

Another stuff, i didnt see windows in where i must make the choose and chatgpt advice me to edit this file sudo nano /etc/grub.d/40_custom and add this into it menuentry "Windows 7" { insmod ntfs set root=(hd0,1) drivemap -s (hd0) ($root) ntldr /bootmgr }

WHen i do that, it now show me the windows in when i click on it shot me that hd0,1 not found.

So i see some reply i will try and see if i can resolve this issue. another update i install a virtual machine in the ubuntu i thought that i can access my old windows file into it but i cant.

Another Update i followed to rebuild bcd also with these commands bootrec.exe /FixMbr successfull bootrec.exe /FixBoot successfull bootrec.exe /RebuildBcd After scaning windows disk installation ask to press Y, and it show me the requested system device cannot be found.

As requested that is my gparted screenshot: enter image description here

Please [edit] your question and include everything in the question if possible. When I try the link I get "You need to be logged in to view this paste." If this is text, copy&paste it into the question and format it as a code block, e.g. by inserting 3 tilde characters `~~~` or 3 backticks as separate lines before and after the code.

Windows is in legacy mode, Ubuntu should be booted and installed in legacy too. How the ubuntu install media boots depends upon machine settings, set it to legacy before UEFI.

You need to first move boot flag from the ESP, sda7 back to sda1, if sda1 is or was Windows boot partition. Windows has to see a NTFS partition with boot flag to make repairs.

@ubfan1 when i put it in legacy mode i cant even start the ubuntu and it show me boot device not found. Please install an operating system on your hard drive.

With the gdisk or fdisk partition utility, first select x for expert mode, then ? or m for help and see that "a" (gdisk attributes) or "A" (fdisk toggle boot flag) gives you the ability to turn on or off the boot flag on a partition. Save results. Ensure your machine is set to legacy boot, and Windows should boot (its bootloader is still in the MBR). Installing grub from grub-pc (not the grub-efi package) should include a legacy Windows in the grub menu.

reboot by windows USB flash drive, select repair and fix boot or select boot directly to windows from the hared disk. after that when you login to windwas use easybcd to put windows bootloader in the right place. restart the pc by boot-repair to put ubuntu and windows in the boot menu.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
