Strongly recommend using the script by leitbogioro
The success rate is as high as 100% for 512M memory and above. It can automatically configure ipv6

I want to DD to a Linux system, but the memory is only 256M#

In practice, only the script by moeclub can be used
Note ⚠️ This script does not support ipv6 and can only automatically configure ipv4 ⚠️

bash <(wget --no-check-certificate -qO- 'https://moeclub.org/attachment/LinuxShell/InstallNET.sh') -d 9 -v 64 -a

Password MoeClub.org

I recommend using the script by leitbogioro
Prerequisite: have vnc, memory not too low. Supports automatic configuration of v4v6

bash <(curl -sSL https://raw.githubusercontent.com/leitbogioro/Tools/master/Linux_reinstall/InstallNET.sh) -windows 2019  -lang "cn"

If you want to d other versions, just change it to -windows 10/11/2012/2016/2019/2022
Password Teddysun.com

I want to DD to Windows, but do not have VNC#

If you do not have vnc, then you can use the 5k script.
